Description Jakub Jelinek 2007-02-09 11:02:11 UTC
+++ This bug was initially created as a clone of Bug #227884 +++ Description of problem: (From firstname.lastname@example.org) Some customers consider tzdata 2005m changes as "the upcoming DST" changes, as if tzdata did not change 20 times or so a year. So guess the question is if gcj has its own tzdata copy like the various proprietary JVMs have and its own tzdata parser. I see something what looks like a tzdata file parser in libjava/java/util/VMTimeZone.java (and libjava/classpath/vm/reference/java/util/VMTimeZone.java), but am not sure what exactly it is used for and whether that reads just /etc/localtime, or other /usr/share/zoneinfo/ files too. Additionally there seems to be a hardcoded extremely simplified data in libjava/classpath/java/util/TimeZone.java, apparently generated with libjava/classpath/scripts/timezones.pl from tzdata and very outdated. I rerun that script on tzdata2007a to see what the differences would be and patch is attached. More importantly, I wonder whether it really has to have a pregenerated table compiled in, whether that's not something it should create on the fly by reading /usr/share/zoneinfo/ files. Version-Release number of selected component (if applicable): RHEL4.4 -- Additional comment from email@example.com on 2007-02-08 14:32 EST -- Created an attachment (id=147693) libgcj patch for DST timezone changes -- Additional comment from firstname.lastname@example.org on 2007-02-09 05:48 EST -- That patch was against trunk and, furthermore, isn't the latest. There is a newer patch against trunk at http://gcc.gnu.org/ml/gcc-patches/2007-02/msg00800.html which I'm going to backport. Apparently there are several bugs in the TimeZone code, but those need a lot of work and aren't appropriate for the update now, so guess just the updated tables should be enough for RHEL4.5. gcc4 packages also include their own libgcj4 with the same problem.

Testcase in #227884, just change gcj to gcj4 and gij to gij4 in the instructions.
Comment 3 Jakub Jelinek 2007-02-09 19:35:51 UTC
Built as gcc4-4.1.1-52.EL4.
