Your best bet is probably finding a way to query the TZ database directly to get this information. The C library calls don't directly support looking up the switchover so this might not be real easy to do. You can probably pull up the data from the raw or compiled zoneinfo files. http://en.wikipedia.org/wiki/Tz_database Some APIs exist for this in DateTime: http://search.cpan.org/dist/DateTime- TimeZone/lib/DateTime/TimeZone/OlsonDB.pm But one of the sentences in the docs says: USAGE-- Not yet documented. This stuff is a mess. > Thanks again! > Best regards, > Guustaaf Regards, Matthew Hall
