+
+# From Ephraim Silverberg (April 18, 1989):
+
+# Prior to 1989, the rules concerning Daylight Savings Time changed every
+# year; as information, regarding exact times and dates during this period,
+# is not readily available at the present time, the rules commence starting
+# with the year 1989.
+
+# From 1989 onwards the rules are as follows:
+#
+# 1. Daylight Savings Time commences midnight of the first Saturday night
+#    following the seven-day festival of Pesach (Passover).  The transition
+#    is from midnight Israel Standard Time to 1 a.m. Israel Daylight Savings
+#    time.  As the Pesach festival is dependent on the Lunar calendar (the
+#    first day is always on the 15th day of the month of Nisan), the rule
+#    changes every year on the Gregorian calendar.
+#
+# 2. Standard Time is reinstated on the Saturday night whereupon Jews
+#    following the Ashkenazi (European) rite begin to recite the Selichot
+#    (forgiveness) prayers prior to the Jewish Lunar New Year.  The transition
+#    is from midnight Israel Daylight Savings time to 11 p.m. Israel Standard
+#    Time.  The law (according to the Ashkenazi custom) concerning the
+#    commencement of the Selichot prayers is described in chapter 128, section
+#    5 of the "Code of Jewish Law," by Rabbi Shlomo Ganzfried (translated by
+#    Hyman E. Goldin):
+#
+#       Beginning with the Sunday [**] before Rosh Hashanah [***],
+#       we rise early for the service of Selichot (supplications for
+#       forgiveness).  If Rosh Hashanah occurs on Monday or Tuesday, we
+#       begin saying the Selichot from the Sunday of the preceding week.
+#
+#    This, too, varies from year to year on the Gregorian calendar and, thus,
+#    two explicit timezone rules are required for each Gregorian year.
+#
+#    [**] actually Saturday night as the Jewish day commences at nightfall.
+#    [***] the Jewish Lunar New Year.

+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information

+# ...standardization on DST in Europe started in about 1977 with switches on

+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March.  And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in

+# dates...
+# 
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe.  Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using formulas in the U.S. Naval Observatory's
+# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
+# [plus or minus two] seconds during the current year."
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+#	eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+#		-12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+#		+ 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+#	l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+.Sh SYNOPSIS
+.Fd #include <tzfile.h>
+.Sh DESCRIPTION
+The time zone information files used by
+.Xr tzset 3
+begin with bytes reserved for future use,
+followed by four four-byte values of type
+.Em long ,
+written in a ``standard'' byte order
+(the high-order byte of the value is written first).
+These values are,
+in order:
+.Bl -tag -width tzh_ttisstdcnt
+.It Fa tzh_ttisstdcnt
+The number of standard/wall indicators stored in the file.
+.It Fa tzh_leapcnt
+The number of leap seconds for which data is stored in the file.
+.It Fa tzh_timecnt
+The number of "transition times" for which data is stored
+in the file.
+.It Fa tzh_typecnt
+The number of "local time types" for which data is stored
+in the file (must not be zero).
+.It Fa tzh_charcnt
+The number of characters of "time zone abbreviation strings"
+stored in the file.
+.El
+.Pp
+The above header is followed by
+.Fa tzh_timecnt
+four-byte values of type
+.Em long ,
+sorted in ascending order.
+These values are written in ``standard'' byte order.
+Each is used as a transition time (as returned by
+.Xr time 2 )
+at which the rules for computing local time change.
+Next come
+.Fa tzh_timecnt
+one-byte values of type
+.Fa unsigned char ;
+each one tells which of the different types of ``local time'' types
+described in the file is associated with the same-indexed transition time.
+These values serve as indices into an array of
+.Fa ttinfo
+structures that appears next in the file; 
+these structures are defined as follows:
+.Bd -literal -offset indent
+struct ttinfo {	
+	long	tt_gmtoff;
+	int	tt_isdst;
+	unsigned int	tt_abbrind;
+};
+.Ed
+.Pp
+Each structure is written as a four-byte value for
+.Fa tt_gmtoff
+of type
+.Em long ,
+in a standard byte order, followed by a one-byte value for
+.Fa tt_isdst
+and a one-byte value for
+.Fa tt_abbrind .
+In each structure,
+.Fa tt_gmtoff
+gives the number of seconds to be added to
+.Tn GMT ,
+.Fa tt_isdst
+tells whether
+.Fa tm_isdst
+should be set by
+.Xr localtime 3
+and
+.Fa tt_abbrind
+serves as an index into the array of time zone abbreviation characters
+that follow the
+.Fa ttinfo
+structure(s) in the file.
+.Pp
+Then there are
+.Fa tzh_leapcnt
+pairs of four-byte values, written in standard byte order;
+the first value of each pair gives the time
+(as returned by 
+.Xr time 2 )
+at which a leap second occurs;
+the second gives the
+.Em total
+number of leap seconds to be applied after the given time.
+The pairs of values are sorted in ascending order by time.
+.Pp
+Finally there are
+.Fa tzh_ttisstdcnt
+standard/wall indicators, each stored as a one-byte value;
+they tell whether the transition times associated with local time types
+were specified as standard time or wall clock time,
+and are used when a time zone file is used in handling
+.Tn POSIX Ns -style
+time zone environment variables.
+.Pp
+.Fa Localtime
+uses the first standard-time
+.Fa ttinfo
+structure in the file
+(or simply the first
+.Fa ttinfo
+structure in the absence of a standard-time structure)
+if either
+.Fa tzh_timecnt
+is zero or the time argument is less than the first transition time recorded
+in the file.

+is
+.BR \- ,
+the standard input is read.
+.PP
+These options are available:
+.TP
+.BI "\-d " directory
+Create time conversion information files in the named directory rather than
+in the standard directory named below.
+.TP
+.BI "\-l " timezone
+Use the given time zone as local time.
+.I Zic
+will act as if the input contained a link line of the form
+.sp
+.ti +.5i
+Link	\fItimezone\fP		localtime
+.TP
+.BI "\-p " timezone
+Use the given time zone's rules when handling POSIX-format

+.I Zic
+will act as if the input contained a link line of the form
+.sp
+.ti +.5i
+Link	\fItimezone\fP		posixrules
+.TP
+.BI "\-L " leapsecondfilename
+Read leap second information from the file with the given name.
+If this option is not used,
+no leap second information appears in output files.
+.TP
+.B \-v
+Complain if a year that appears in a data file is outside the range
+of years representable by
+.IR time (2)
+values.
+.TP
+.B \-s
+Limit time values stored in output files to values that are the same
+whether they're taken to be signed or unsigned.
+You can use this option to generate SVVS-compatible files.
+.sp
+Input lines are made up of fields.
+Fields are separated from one another by any number of white space characters.
+Leading and trailing white space on input lines is ignored.
+An unquoted sharp character (#) in the input introduces a comment which extends
+to the end of the line the sharp character appears on.
+White space characters and sharp characters may be enclosed in double quotes
+(") if they're to be used as part of a field.
+Any line that is blank (after comment stripping) is ignored.
+Non-blank lines are expected to be of one of three types:
+rule lines, zone lines, and link lines.
+.PP
+A rule line has the form
+.nf
+.B
+.ti +.5i
+.ta \w'Rule\0\0'u +\w'NAME\0\0'u +\w'FROM\0\0'u +\w'1973\0\0'u +\w'TYPE\0\0'u +\w'Apr\0\0'u +\w'lastSun\0\0'u +\w'2:00\0\0'u +\w'SAVE\0\0'u

+Rule	NAME	FROM	TO	TYPE	IN	ON	AT	SAVE	LETTER/S
+.sp
+For example:
+.ti +.5i
+.sp
+Rule	USA	1969	1973	\-	Apr	lastSun	2:00	1:00	D
+.sp
+.fi
+The fields that make up a rule line are:
+.TP "\w'LETTER/S'u"
+.B NAME
+Gives the (arbitrary) name of the set of rules this rule is part of.
+.TP
+.B FROM
+Gives the first year in which the rule applies.
+The word
+.B minimum
+(or an abbreviation) means the minimum year with a representable time value.
+The word
+.B maximum
+(or an abbreviation) means the maximum year with a representable time value.
+.TP
+.B TO
+Gives the final year in which the rule applies.
+In addition to
+.B minimum
+and
+.B maximum
+(as above),
+the word
+.B only
+(or an abbreviation)
+may be used to repeat the value of the
+.B FROM
+field.
+.TP
+.B TYPE
+Gives the type of year in which the rule applies.
+If
+.B TYPE
+is
+.B \-
+then the rule applies in all years between
+.B FROM
+and
+.B TO
+inclusive;
+if
+.B TYPE
+is
+.BR uspres ,
+the rule applies in U.S. Presidential election years;
+if
+.B TYPE
+is
+.BR nonpres ,
+the rule applies in years other than U.S. Presidential election years.
+If
+.B TYPE
+is something else, then
+.I zic
+executes the command
+.ti +.5i
+\fByearistype\fP \fIyear\fP \fItype\fP
+.br
+to check the type of a year:
+an exit status of zero is taken to mean that the year is of the given type;
+an exit status of one is taken to mean that the year is not of the given type.
+.TP
+.B IN
+Names the month in which the rule takes effect.
+Month names may be abbreviated.
+.TP
+.B ON
+Gives the day on which the rule takes effect.
+Recognized forms include:
+.nf
+.in +.5i
+.sp
+.ta \w'Sun<=25\0\0'u
+5	the fifth of the month
+lastSun	the last Sunday in the month
+lastMon	the last Monday in the month
+Sun>=8	first Sunday on or after the eighth
+Sun<=25	last Sunday on or before the 25th
+.fi
+.in -.5i
+.sp
+Names of days of the week may be abbreviated or spelled out in full.
+Note that there must be no spaces within the
+.B ON
+field.
+.TP
+.B AT
+Gives the time of day at which the rule takes effect.
+Recognized forms include:
+.nf
+.in +.5i
+.sp
+.ta \w'1:28:13\0\0'u
+2	time in hours
+2:00	time in hours and minutes
+15:00	24-hour format time (for times after noon)
+1:28:14	time in hours, minutes, and seconds
+.fi
+.in -.5i
+.sp
+Any of these forms may be followed by the letter
+.B w
+if the given time is local
+.q "wall clock"
+time or
+.B s
+if the given time is local
+.q standard
+time; in the absence of
+.B w
+or
+.BR s ,
+wall clock time is assumed.
+.TP
+.B SAVE
+Gives the amount of time to be added to local standard time when the rule is in
+effect.
+This field has the same format as the
+.B AT
+field
+(although, of course, the
+.B w
+and
+.B s
+suffixes are not used).
+.TP
+.B LETTER/S
+Gives the
+.q "variable part"
+(for example, the
+.q S
+or
+.q D
+in
+.q EST
+or
+.q EDT )
+of time zone abbreviations to be used when this rule is in effect.
+If this field is
+.BR \- ,
+the variable part is null.
+.PP
+A zone line has the form
+.sp
+.nf
+.ti +.5i
+.ta \w'Zone\0\0'u +\w'Australia/South\-west\0\0'u +\w'GMTOFF\0\0'u +\w'RULES/SAVE\0\0'u +\w'FORMAT\0\0'u
+Zone	NAME	GMTOFF	RULES/SAVE	FORMAT	[UNTIL]
+.sp
+For example:
+.sp
+.ti +.5i
+Zone	Australia/South\-west	9:30	Aus	CST	1987 Mar 15 2:00
+.sp
+.fi
+The fields that make up a zone line are:
+.TP "\w'GMTOFF'u"
+.B NAME
+The name of the time zone.
+This is the name used in creating the time conversion information file for the
+zone.
+.TP
+.B GMTOFF
+The amount of time to add to GMT to get standard time in this zone.
+This field has the same format as the
+.B AT
+and
+.B SAVE
+fields of rule lines;
+begin the field with a minus sign if time must be subtracted from GMT.
+.TP
+.B RULES/SAVE
+The name of the rule(s) that apply in the time zone or,
+alternately, an amount of time to add to local standard time.
+If this field is
+.B \-
+then standard time always applies in the time zone.
+.TP
+.B FORMAT
+The format for time zone abbreviations in this time zone.
+The pair of characters
+.B %s
+is used to show where the
+.q "variable part"
+of the time zone abbreviation goes.
+.TP
+.B UNTIL
+The time at which the GMT offset or the rule(s) change for a location.
+It is specified as a year, a month, a day, and a time of day.
+If this is specified,
+the time zone information is generated from the given GMT offset
+and rule change until the time specified.
+.IP
+The next line must be a
+.q continuation
+line; this has the same form as a zone line except that the
+string
+.q Zone
+and the name are omitted, as the continuation line will
+place information starting at the time specified as the
+.B UNTIL
+field in the previous line in the file used by the previous line.
+Continuation lines may contain an
+.B UNTIL
+field, just as zone lines do, indicating that the next line is a further
+continuation.
+.PP
+A link line has the form
+.sp
+.nf
+.ti +.5i
+.if t .ta \w'Link\0\0'u +\w'LINK-FROM\0\0'u
+.if n .ta \w'Link\0\0'u +\w'US/Eastern\0\0'u
+Link	LINK-FROM	LINK-TO
+.sp
+For example:
+.sp
+.ti +.5i
+Link	US/Eastern	EST5EDT
+.sp
+.fi
+The
+.B LINK-FROM
+field should appear as the
+.B NAME
+field in some zone line;
+the
+.B LINK-TO
+field is used as an alternate name for that zone.
+.PP
+Except for continuation lines,
+lines may appear in any order in the input.
+.PP
+Lines in the file that describes leap seconds have the following form:
+.nf
+.B
+.ti +.5i
+.ta \w'Leap\0\0'u +\w'YEAR\0\0'u +\w'MONTH\0\0'u +\w'DAY\0\0'u +\w'HH:MM:SS\0\0'u +\w'CORR\0\0'u
+Leap	YEAR	MONTH	DAY	HH:MM:SS	CORR	R/S
+.sp
+For example:
+.ti +.5i
+.sp
+Leap	1974	Dec	31	23:59:60	+	S
+.sp
+.fi
+The 
+.BR YEAR ,
+.BR MONTH ,
+.BR DAY ,
+and
+.B HH:MM:SS
+fields tell when the leap second happened.
+The
+.B CORR
+field
+should be
+.q +
+if a second was added
+or 
+.q -
+if a second was skipped.
+The
+.B R/S
+field
+should be (an abbreviation of)
+.q Stationary
+if the leap second time given by the other fields should be interpreted as GMT
+or
+(an abbreviation of)
+.q Rolling
+if the leap second time given by the other fields should be interpreted as
+local wall clock time.
+.SH NOTE
+For areas with more than two types of local time,
+you may need to use local standard time in the
+.B AT
+field of the earliest transition time's rule to ensure that
+the earliest transition time recorded in the compiled file is correct.
