+.Os
+.Dt CFTIME 3
+.Sh NAME
+.Nm cftime
+.Nm ascftime
+.Nd convert date and time to string
+.Sh SYNOPSIS
+.Fd #include <time.h>
+.Ft int
+.Fn cftime "char *s" "char *format" "const time_t *clock"
+.Ft int
+.Fn ascftime "char *s" "const char *format" "const struct tm *tmptr"
+.Sh DESCRIPTION
+.Bf -symbolic
+The cftime and ascftime functions are made obsolete by strftime(3).
+.br
+They are available from the compatibility library, libcompat.
+.Ef
+.Pp
+Use of the functions
+.Nm cftime
+and
+.Nm ascftime
+is strongly deprecated, since there is no way to check for a buffer
+overflow condition. Use
+.Xr strftime 3
+instead.
+
+.Nm Ascftime
+is almost identical with
+.Xr strftime 3 ,
+with the only exception there's no parameter to tell about the
+maximal buffer length, and the
+.Fa format
+parameter defaults to
+.Dq %C
+if a
+.Em NULL
+pointer is given.
+
+.Nm Cftime
+does the same job, but it first invokes
+.Xr localtime 3
+in order to convert the given
+.Fa clock ,
+then also performs the conversions as requested by the
+.Fa format
+argument.
+
+.Sh RETURN VALUES
+The
+.Nm cftime
+and
+.Nm ascftime
+functions return the number of characters written to the output
+buffer
+.Fa s ,
+not counting the trailing null character.
+
+.Sh SEE ALSO
+.Xr localtime 3 ,
+.Xr strftime 3 .
