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.
