Time zone and daylight-saving rules are controlled by individual governments. They are sometimes changed with little notice, and their histories and planned futures are often recorded only fitfully.

Here is a summary of attempts to organize and record relevant data in this area. The public-domain time zone database contains code and data that represent the history of local time for many representative locations around the globe.

It is updated periodically to reflect changes made by political bodies to time zone boundaries and daylight saving rules.

Each main entry in the database represents a timezone for a set of civil-time clocks that have all agreed since Timezones are typically identified by continent or ocean and then by the name of the largest city within the region containing the clocks.

The database also records when daylight saving time was in use, along with some time zone abbreviations such as EST for Eastern Standard Time in the US.

Untagged commits are less well tested and probably contain more errors. The code lets you compile the tz source files into machine-readable binary files, one for each location. The code also lets you read a TZif file and interpret timestamps for that location.

The tz code and data are by no means authoritative. If you find errors, please send changes to tz iana. You can also subscribe to it and browse the archive of old messages. Metadata for mailing list discussions and corresponding data changes can be generated automatically.

If your government plans to change its time zone boundaries or daylight saving rules, inform tz iana. With less than a year's notice there is a good chance that some computer-based clocks will operate incorrectly after the change, due to delays in propagating updates to software and data.

The shorter the notice, the more likely clock problems will arise; see " On the Timing of Time Zone Changes " for examples. Changes to the tz code and data are often propagated to clients via operating system updates, so client tz data can often be corrected by applying these updates. More detail can be found in Theory and pragmatics of the tz code and data. A0 TimeZone Migration displays changes between recent tzdb versions.

If you want, you can also get a feel for the timezone by asking the browser Josh Fraser has a nice write up on it here. The second thing that you need to know is whether the location observes daylight savings time DST or not. Since DST is always observed during the summer, we can compare the time offset between two dates in January, to the time offset between two dates in June. If the offsets are different, then we know that the location observes DST. Here is a SO questions that touch on getting the timezone from javascript.
