Solution 3

As you want to trigger recalculation on change in time, handle the event DateTimePicker.ValueChanged.

Solution 1

Why not use the Leave[^] event of your DateTimePicker[^] controls? Out of curiosity, is this your personal application? Because if its not, its not a wise move to use datetimepicker as people may cheat their login/logout. :)
