- From a human's perspective, "a day from now" is always potentially
unambigous, just like "a month from now" or "a year from now", whereas
"24 hours from now" is never so.  In a given application, a user who
doesn't care can always write a helper function to generate hours;  in an
applicatino whose developer who *does* care, the 'days' argument to
timedelta in its current does *not* help achieve her goal:  it is an
attractive nuisance she will have to learn to avoid.
