DateTime control default behaviour

Problem: The SharePoint date time control's default behaviour is to returns the current date and time when no date has been selected.
Initial Hypothesis: Validate the control to pre insert to check if it is selected, if no date time is choosen don't update the record.
Resolution:  The Property IsDateEmpty returns "false" if the date has been input.
Code:
if (!dtMyBirthday.IsDateEmpty)  { // ... User has delected their birthday date so insert into SQL table or list }
