NOTE:
	The following refers to AT&T's UNIX(tm).  It may or may not also
apply to Berkeley versions.

	I would like to know how UNIX installations outside of the U.S.A.
manage Day Light Savings  in their ctime(3C) routines.  There  is code in
tzset() (which  is called by all of the ctime routines) to move the clock
ahead (back) at the appropriate time of the year.
	I know that some other countries  move their clocks  at different
times of the year  from us.  Also, some  countries have time  zones which
are not in hour  jumps, but  increments of  15 or 30 minutes.  I am  very
curious as to how UNIX sites outside of the U.S.A. have  accommodated the
assumptions built into ctime.  If you haven't had to modify ctime because
the assumptions work in your country,  I'd also be  interested in hearing
that.
	Please mail me your responses; it's probably not worth cluttering
up the net just to satisfy my curiosity.
	As usual, thanks in advance.
