-.Sh NAME
-.Nm tzfile
-.Nd timezone information
-.Sh SYNOPSIS
-.Fd #include \&"/usr/src/lib/libc/stdtime/tzfile.h\&"
-.Sh DESCRIPTION
-The time zone information files used by
-.Xr tzset 3
-begin with the magic characters
-.Dq Li TZif
-to identify them as
-time zone information files,
-followed by a character identifying the version of the file's format
-(as of 2005, either an ASCII NUL or a '2')
-followed by fifteen bytes containing zeroes reserved for future use,
-followed by four four-byte values
-written in a ``standard'' byte order
-(the high-order byte of the value is written first).
-These values are,
-in order:
-.Pp
-.Bl -tag -compact -width tzh_ttisstdcnt
-.It Va tzh_ttisgmtcnt
-The number of UTC/local indicators stored in the file.
-.It Va tzh_ttisstdcnt
-The number of standard/wall indicators stored in the file.
-.It Va tzh_leapcnt
-The number of leap seconds for which data is stored in the file.
-.It Va tzh_timecnt
-The number of ``transition times'' for which data is stored
-in the file.
-.It Va tzh_typecnt
-The number of ``local time types'' for which data is stored
-in the file (must not be zero).
-.It Va tzh_charcnt
-The number of characters of ``time zone abbreviation strings''
-stored in the file.
-.El
-.Pp
-The above header is followed by
-.Va tzh_timecnt
-four-byte values of type
-.Fa 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 3 )
-at which the rules for computing local time change.
-Next come
-.Va 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 (with
-.Fa tzh_typecnt
-entries) that appears next in the file;
-these structures are defined as follows:
-.Pp
-.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
-.Va tt_gmtoff
-of type
-.Fa long ,
-in a standard byte order, followed by a one-byte value for
-.Va tt_isdst
-and a one-byte value for
-.Va tt_abbrind .
-In each structure,
-.Va tt_gmtoff
-gives the number of seconds to be added to UTC,
-.Li tt_isdst
-tells whether
-.Li tm_isdst
-should be set by
-.Xr localtime 3
-and
-.Va tt_abbrind
-serves as an index into the array of time zone abbreviation characters
-that follow the
-.Li ttinfo
-structure(s) in the file.
-.Pp
-Then there are
-.Va 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 3 )
-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
-Then there are
-.Va 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 POSIX-style
-time zone environment variables.
-.Pp
-Finally there are
-.Va tzh_ttisgmtcnt
-UTC/local indicators, each stored as a one-byte value;
-they tell whether the transition times associated with local time types
-were specified as UTC or local time,
-and are used when a time zone file is used in handling POSIX-style
-time zone environment variables.
-.Pp
-.Nm localtime
-uses the first standard-time
-.Li ttinfo
-structure in the file
-(or simply the first
-.Li ttinfo
-structure in the absence of a standard-time structure)
-if either
-.Li tzh_timecnt
-is zero or the time argument is less than the first transition time recorded
-in the file.
-.Pp
-For version-2-format time zone files,
-the above header and data is followed by a second header and data,
-identical in format except that eight bytes are used for each
-transition time or leap second time.
-After the second header and data comes a newline-enclosed,
-POSIX-TZ-environment-variable-style string for use in handling instants
-after the last transition time stored in the file
-(with nothing between the newlines if there is no POSIX representation for
-such instants).
