Dear Sir @Pstork1
Thanks for your kind explanation about the backend work of the date time picker,
Actually there is a 5 Hour Difference in the values saved in PowerApps as compared with the Excel.
but I wanted to do the conversion while entering it into the excel, as Sir @WarrenBelz said, I have to use TimeZoneOfffset Function,
but I am confused where should I drop that formula in?
HourValue1: OnSelect Property on that Hour Value of Time Picker or in MinuteValue1 onSelect Property?
or by Selecting the Whole Date Time Picker DataCard
and put the function in Update Property?
Right its using this Code in the Update Property:
DateValue1.SelectedDate + Time(Value(HourValue1.Selected.Value), Value(MinuteValue1.Selected.Value), 0)
Kindly Guide me!
