The rrule is for 8am, BYHOUR=08. However, 06 AM (as generated by the function) in UTC is 09 AM in Africa/Cairo which is incorrect. It should be 5am.

I think it is due to the tz datatime that is currently being used. Would be willing to investigate it myself if you give the go ahead.

Feel free to take a look. This library calls our to the rust based rrule, so if there's an issue that's a good place to investigate
