Displaying and saving time in 12 hour AM/PM format

When Power Apps sets up a Date/Time field, the hours are in 24 hour format. Have you ever wanted to work with a 12 hour AM/PM choice and display for the user ? Here is how

Add another drop-down at the right with Items

["AM", "PM"]

and the Default of this drop-down

If(
   Hour(Parent.Default) < 12, 
   "AM", 
   "PM"
)

Then you need to change the Items of the Hour drop-down to

["12","01","02","03","04","05","06","07","08","09","10","11"]

and the Default of the Hour drop-down

With(
   {
      _Hour:
      Mod(
         Hour(Parent.Default),
         12
      )
   },
   Text(
      If(
         _Hour = 0, 
         12,
         _Hour 
      ),
      "00"
   )
)

Now the Update of the Data Card for the Hour dropdown

DatePickerName.SelectedDate + 
Time(
   If(
      AmPmDropdown.Selected.Value = "PM", 
      12, 
      0
   ) + 
   Mod(
      Value(
         HourDropdown.Selected.Value
      ), 
      12
   ), 
   Value(
      MinuteDropdown.Selected.Value
   ),
   0
)

This all should now allow you to perform this function
