Approval time of day

I know this is very specific but I have a question for those who have been recently approved for their i765, what time of the day did you check your USCIS online and see the status change to “approved” ? I’m one of the unlucky ones that applied mid April and I catch myself checking my USCIS every hour every day. I’m curious if they just update the statuses once a day or if it’s randomly through the day? It’s getting closer to my current cards expiration so I’m getting a bit anxious.
