Question

What I want to do: Implement a localizable clock in javascript. The idea is that the user would select a town, and the clock would display current local time, taking into account daylight saving data.

Question: Is there a reliable web service, or alternatively a library that I should update from time to time that would provides the two things listed below ?

• A set of named locations.
• A process that gives me the timezone and the daylight saving data for a given location.

Note: This is meant to be in a gadget where I have no server-side support, so I need a pure javascript solution or a public web service.

Answer 1

• pure JavaScript solution: timezone-js
• public web-service http://www.earthtools.org/webservices.htm#timezone
