Does anyone know a webservice that converts a timezone string to the corresponding GMT Offset?
Meaning I like to send a HTTP request like this:
http://servcer.com/getgmtoffset?timezone=Europe/Zurich
and get "+1" returned.
Why external service?
I'm writing a google apps script, where the API does not have such conversion options and I prefer not to update the conversion table myself, when countries decide to use different daylight saving time parameters.
