[What is the time zone of fiverr for Evaluation period to promote sellers on next level]

To my experience, you will receive notification 12 hrs after 00:00 GMT.

The server needs time to arrange many things so you can expect to be promoted on 2pm your time.

I had completed the next level requirements at 11:00 am on 15, August. 2019.

I had 89% my completion rate but got 90% at 11:00 am but still got demoted at 2:00 pm

What is the reason ?
