SubmitForm() updating SharePoint Event with different time

[Anonymous]

I have a PowerApps that is providing views, the ability to submit new events, and the ability to edit events.  What I have found is that when a user in the application enters a time into form within PowerApps, it will display fine in PowerApps (for instance if they stay the event starts at 9PM and runs to 10PM).  However, when you look at what is in the actual SharePoint list, it is 3 hours behind (so it shows the event from 6PM to 7PM).  Seems to be a difference between the time that my PowerApps is in and the time that the users are in.

To update an event or create a new event, I'm using SubmitForm() as the event has quite a few custom fields.  As such it would be a lengthly Patch() statement.
