The good people at “the tz database” project released their first update for this year (2011a). I have updated TZDB to include the newest update. No code changes in this release (it is the same 1.7 code base), just updated the timezone database.
For those unaware: TZDB is an open source project that provides Delphi (7+) and FreePascal (2.0+) users with a “built-in” timezone database. The same source of data is used in most Unixes, Java, MacOS and multiple other projects out there.
