Hey @z_mike_90
Yes, if you dont set the time, then the flow runs at UTC.
So, below I made a manual flow. In the second step I took a compose and saved the time at which the flow was triggered. By putting the dynamic field of timestamp at which the flow was triggered. And it showed utc.
But, as you are triggering the flow manually, its running at that instant. So, you can say it ran at that utc time, but it also ran at your time.
If you take any time in power automate it will show it in utc. So, you will have to convert the time.


And for a recurrence flow, if you dont set a time zone, it will run at utc.
I hope this helps. 🙂
