Releases · pavkam/tzdb

This release sees a completely rewritten core that moves away from TCompiledPeriod/TCompiledRule combo. Now, the code scans the data structures on each request. The consequence of this change was to finally take into consideration all possible combinations of year segments and rules.

This change finally allows TZDB to support all exotic combinations of rules and zones!

This is a highly recommended update.

TZDB 2.0.2019b

This is a breaking release.

TBudledTimeZone no longer derives from TTimeZone on Delphi.
Implementation now uses generic classes on both Delphi and FreePascal.
Dropped support for versions of Delphi pre-XP. Minimum supported FreePascal version is 3.0.
Rewrote internals to use year segments for all TZ functions. Before, each operation would have its own quirks and impl. details.
GetYearBreakdown allows pulling all year segments for a given year. No more looping by second required!
New DbVersion property allows checking the IANA DB version.
General fixes for exotic time zones such as Cairo in 1900, 2010, 2012 and 2014.
Fixes for zones with negative DST offsets (Dublin).
... and more fixes!
