Timezone list with GMT offset


I have an APEX application that uses the API to create webinars in Zoom.
For this purpose, I need to replicate the timezone list provided in my Zoom account.
I understand that this list can be retrieved from here-

However, this list doesn’t have the GMT offset which might confuse the user of the APEX application.
Is there any way to retrieve the timezone list with GMT information?

Thank you.

Hey @priya.jetley,

If you would like to create the Webinar with the GMT offset in the start_time don’t include the timezone property, and set the start_time in the GMT format: YYYY-MM-DDTHH:MM:SSZ.

For example, if I create the following Webinar using GMT:

  "topic": "Test GMT",
  "type": 5,
  "start_time": "2020-01-20T06:00:00Z",
  "duration": "60"

GMT Time is 6 am, and my Zoom Account (set to Denver time) shows as 11pm.

So if you have the Z at the end of the start_time it will create the meeting in GMT.

Does that answer your question?
