Getting GMT, or Timezone offset to GMT

[JasperGoes]

Are there any easy ways to get a phones offset to GMT without touching a server and finding its offset that way?

I need all collected data to be in-line with timestamps, without any hiccups when changing timezone.

Thanks (:

[Edit]: I forgot to mention dateObj.getTimeZoneOffset() doesnt seem to work on the devices. (N97 & Mini)

Is there some special situation where getTimezoneOffset fails?

getTimezoneOffset returns the offset in minutes in a quite fancy way e.g. you will get -180 for GMT+3

var date = new Date()
var inhours = -date.getTimezoneOffset()/60;
alert("The local time zone is: GMT " + inhours);

Tested with N97 mini
