I made up a patch for zoneinfo/America/Managua, which we are using by now. You can find it at: http://www.magma.com.ni/sw/time/ It is based on adding the following two entries in /glibc-2.3.2/timezone/northamerica: -6:00 - CST 2005 Apr 10 00:00 -6:00 Nic C%sT I have seen however problems with php too, as well as I suspect that java maintains it's own timezoneinfo. Also, I still have no further notice by now, when the timezone-change will end. Best Regards, Jorge-León P.S.: please apologize for beeing terse and replying late. I *will* try to keep track of this issue and keep you informed. Please identify to whom to report. GOTO Masanori <gotom@debian.or.jp> writes:

The DST has no ending date! It is said, that there will be a testing period of two months...

Please consider to check this timezone change.
Thanks in advance, -- gotom

Thanks for reporting this. (But surely you needed to add a Rule line as well?) I have circulated some proposed patches on the tz mailing list and expect they'll be installed in due course onto the canonical copies at <ftp://elsie.nci.nih.gov/pub/>. Here's a summary of the relevant patches I proposed. These patches guess that daylight saving time will expire on September 11, but of course this could change. @@ -1931,11 +1958,28 @@ Zone America/Montserrat -4:08:52 - LMT 1 # Nicaragua seems to be back at -6:00 but I have not been able to find when # they changed from -5:00. # +# From Steffen Thorsen (2005-04-12): +# I've got reports from 8 different people that Nicaragua just started +# DST on Sunday 2005-04-10, in order to save energy because of +# expensive petroleum.

Right! Sorry for not copying them, but they are very similar to yours. How can I stay in sync with this issue? Best Regards, Jorge-León

For the tz database, you can visit <ftp://elsie.nci.nih.gov/pub/>. You can also subscribe to the tz mailing list as described in <http://www.twinsun.com/tz/tz-link.htm> (look for "subscribe"). For Debian, you can visit <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=303920>. (I think you get copies of all further bug reports sent there.)
