Yes, although negative DST support is required by POSIX and has been in tzcode for quite some time, that was the first use of it in tzdata. That change was intended to support Irish Standard Time, which is an hour ahead of GMT (which Ireland uses in winter). We're planning to back that change out temporarily, since we found some issues with it with ICU and with OpenJDK.
What software are you using to parse the data files? Has the problem been reported to the maintainers of that software?
In current version also dst is -ve for europe/dublin
This is correct.
how the dst be negative.. it is always 0 or +1. we are facing issues because on this..
Please read through the several threads on this mailing list about this topic since December/January. I don't believe there is any benefit to having the discussion again.
please correct the dst for europe/dublin.
If you can't correct your software to correctly parse tzdb files with negative dst, you can use the "rearguard" format of tzdb. As discussed (at length) though: negative dst is an unfortunate reality which your software should be able to deal with. Philip -- Philip Paeps Senior Reality Engineer Ministry of Information
