Yes. Conceptually, it does not make sense because class Time does not
represent a magnitude. If you want to think of the time of day as a
magnitude, then class DateAndTime is probably what you want.
The class comment for Time explains:
If you need a point in time on a particular day, use DateAndTime.
If you need a duration of time, use Duration.
