If that's the case, we'd need to create some sort of function to specify
the time unit to output timestamp operation into:
to_weeks(current_timestamp - hire_date) / '2 weeks'
... otherwise division and multiplication operators for time values
don't do us much good, as we'd be forced to integer-ize all intervals
before we can perform any operations on them at all.
