Update.
1998-09-10 11:53 Ulrich Drepper <drepper@cygnus.com> * timezone/Makefile: Add rules to generate Asia/Tokyo zoneinfo files for test. * timezone/tst-timezone.c (tests): Fix typo in last patch. * time/tzfile.c (__tzfile_read): Handle case when there are no transitions. Set __timezone based on computed offset. * time/tzset.c (tzset_internal): Set __timezone before returning. * time/tzset.c (tzset_internal): Optimize handling of local string copy. 1998-09-10 Andreas Jaeger <aj@arthur.rhein-neckar.de> * timezone/tst-timezone.c (tests): Add test for Asia/Tokyo (see PR libc/776). * sysdeps/powerpc/bits/fenv.h: Add parens.
