Hi,
Antonio's formula almost works but in your case two things need to change: you need to see if the value is empty or not and you need to convert to DateTime, not just tdate.
Try this:
if length ({Times_.TimeIn}) > 10 then
cDateTime (left (mydt,instrrev ({Times_.TimeIn},":")-1))
Else DateTime (0, 0, 0, 0, 0, 0);
I used the length to see if the field is empty or not. You can check for other things like a ":" or something else.
If there is a value then it converts the field to a date time. Otherwise it passes a null date time.
