I can see that jam starts at friday at 10:30 and ends at sunday 10:30. But in which timezone? When will jam start in UTC?

thats a goof question.

When will it start in GMT?

The jam will start whenever the timer hits 0. The start time on the main page is different for everyone in different areas. If you are in UTC time, it will show Friday at 09:30 am, if you are in IST time, it will show Friday at 03:00 pm. So you will be fine if you follow the start time of your page.

Thanks!

Alright
