TIMEZONE(3) OpenBSD Programmer's Manual TIMEZONE(3)NAMEtimezone - return the time zone abbreviation
SYNOPSIS
#include <time.h>
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. zone is the number of minutes west of
GMT and dst is non-zero if Daylight Saving Time is in effect.
This function is not used to set the system's time zone. The default
system time zone may be set by running ``zic -l timezone'' as the
superuser.

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