Hi @Shay8080 ,
Do you mean that the time in Excel is different from the time loading in PowerApps?
The reason why you met this problem is that:
Excel's default time zone is UTC.
PowerApps' default time zone is local time zone.
So when PowerApps load time, it will transfer to local time automatically.
In order to solve the problems mentioned above,I suggest you save local time to Excel and load time in PowerApps as local time too. //make time zone the same.
I’ve made a similar test for your reference:
Step1:Set the Default of the Date DATA CARD (not the Default on the Date picker) to
DateAdd(ThisItem.Date,TimeZoneOffset(),Minutes)
Step2:Set the Update of the Date DATA CARD (not the Default Date on the Date picker) to
DateAdd(DateValue10.SelectedDate,-TimeZoneOffset(),Minutes)
Step3:Make sure the Date time zone properties of the date picker control is “Local”
Best Regards,
