Description Alan Matsuoka 2007-02-08 14:34:10 EST
Description of problem:
(From jakub@redhat.com)
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libjava/classpath/scripts/timezones.pl from tzdata and very outdated.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):
RHEL3.8
