I am using nodejs and recently started using moment.timezone to get the timezone offset. I have the following code:
console.log(moment.tz(new Date(), 'Europe/Athens').zone()); // Prints -120
The timezone for 'Europe/Athens' is GMT+2 so i would expect getting '120' and not '-120' and thats what other timezone libraries do.
This issue caused me a serious head scratching bug. It was really easy to fix it once found the problem by just inverting the timezone offset.
Is this a bug on the specific library, or is there a different way to think of zones and offsets? Is there a standard about zone offsets?
This is expected behavior. zone()
returns the offset to UTC relative to the selected timezone.
