Dealing with time is a critical life skill that must be learned.
Having a clock is thus very important.

Keeping the activity separate is good. Once the frame clock
arrives, the activity clock can either be deleted or mutate
into a calendar. The clock activity could also be used to set
the time zone.

If anything, the stopwatch goes with the ruler and the
acoustic ruler.
