From a3931cbec9b380252d89fab3980a9dbb0b2f4152 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 12 Mar 2002 07:50:21 +0000 Subject: [PATCH] Update. 2002-03-07 Jakub Jelinek * time/tst-posixtz.c (tests): Add new tests. (main): Test whether tzset() sets daylight properly. 2002-03-06 Jakub Jelinek * time/tzset.c (tz_compute): Move __daylight, __tzname and __tzname_cur_max setting... (tzset_internal): ...here. 2002-03-06 Jakub Jelinek * time/tzset.c (compute_change): Don't return any value. (tz_compute): Likewise. Don't handle southern hemisphere here.
