timezone(3BSD) (BSD System Compatibility) timezone(3BSD)
NAME
timezone - (BSD) get time zone name given offset from GMT
SYNOPSIS
/usr/ucb/cc [flag . . . ] file . . .
char *timezone(int zone, int dst);
DESCRIPTION
timezone attempts to return the name of the time zone
associated with its first argument, which is measured in
minutes westward from Greenwich. If the second argument is 0,
the standard name is used, otherwise the Daylight Savings Time
version. If the required name does not appear in a table
built into the routine, the difference from GMT is produced;
for instance, in Afghanistan timezone(-(60*4+30), 0) is
appropriate because it is 4:30 ahead of GMT and the string
GMT+4:30 is produced.
REFERENCES
ctime(3C)
NOTICES
The offset westward from Greenwich and an indication of
whether Daylight Savings Time is in effect may not be
sufficient to determine the name of the time zone, as the name
may differ between different locations in the same time zone.
Instead of using timezone to determine the name of the time
zone for a given time, that time should be converted to a
struct tm using localtime [see ctime(3C)] and the tm_zone
field of that structure should be used. timezone is retained
for compatibility with existing programs.
