A while ago I wrote a simple JavaScript library for timezone handling in JavaScript. It provides a simple API described here: https://github.com/dbaron/tz.js/blob/3489978e9422c49f1bb4aafdfeee429a3e66513... and has build scripts to convert the necessary data from the tz database into JSON format to include in the script. The end result including the code and the data, gzip-compressed, is about 74 KB. I keep hoping I'd get a chance to make some additional improvements before announcing it, but that served only to delay announcing it and not to lead to additional improvements. Since it might be useful to others in its current form, I thought I'd share it on this list. It is: https://github.com/dbaron/tz.js -David -- 𝄞 L.
