- The news about this is pretty bad. I have searched endlessly for a
- central source for this information. There is none. Here's the deal:
-
- In the US, going on daylight savings is up to each local government; I
- don't even think it's a state decision since some parts of Indiana do
- and some don't. Currently, the rules in the US are daylight time
- starts at 2am on the first Sunday of April and ends 2am on the last
- Sunday of October. The US Department of Transportation keeps track of
- the rules throughout the US.
-
- Now, international is even worse. Checking with the UN, timezones and
- daylight time rules are kept track of entirely by local regional
- offices of the Commerce, Trade and Transport office (whose name
- changes from region to region) and there is no central collection of
- such information. The UN Library in NY has been asked about this
- information several times and has considered collecting the
- information, but the resources required to collect the information are
- just not there.
-
- So, keeping track of this stuff is other than fun.
