Hi @SCMI4U,
Could you share a screenshot of your Flow configuration?
Could you describe in detail the problems you are currently experiencing?
I am wondering if you have the problem you mentioned in the section on configuring Create event action.
Now that the time is now being calendared two hours early, you could use the addHours() function on the basis of the Start time/End time configuration, adding two hours, so that the time will be the same as expected.
Like:

Please take a try or provide more details, we may provide proper workaround for you.
Best Regards,
Barry
