TIMEZONE(3)						   BSD Library Functions Manual 					       TIMEZONE(3)

NAME
     timezone -- return the timezone abbreviation

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     char *
     timezone(int zone, int dst);

DESCRIPTION
     This interface is for compatibility only; it is impossible to reliably map timezone's arguments to a time zone abbreviation.  See ctime(3).

     The timezone() function returns a pointer to a time zone abbreviation for the specified zone and dst values.  The zone argument is the number
     of minutes west of GMT and dst is non-zero if daylight savings time is in effect.

SEE ALSO
     ctime(3)

HISTORY
     A timezone() function appeared in Version 7 AT&T UNIX.
