  Europe/Dublin also has a negative DST offset. Irish DST runs through the European winter (i.e. the opposite of the other European timezones).

• timeshape

  1 169 6.6 Java

  Java library to find timezone based on geo coordinates

  > The naive way to do so would be via a static mapping of state to time zone but there are a few edge cases that preclude doing this

  More than a few, state is really the wrong resolution here, US timezones follow counties and native reservations borders.

  ZIP codes should probably be good enough but I'd be careful too. If your volume of addresses isn't too crazy, the robust way is to reverse geocode them and use a library that gets you the IANA identifier from timezone shapes.

  https://github.com/RomanIakovlev/timeshape is maintained by a former coworker who could open source some of the work we did internally.
