|
|
Takes two datetime objects and returns the time between d and now
|
|
as a nicely formatted string, e.g. "10 minutes". If d occurs after now,
|
|
then "0 minutes" is returned.
|
|
|
|
Units used are years, months, weeks, days, hours, and minutes.
|
|
Seconds and microseconds are ignored. Up to two adjacent units will be
|
|
displayed. For example, "2 weeks, 3 days" and "1 year, 3 months" are
|
|
possible outputs, but "2 weeks, 3 hours" and "1 year, 5 days" are not.
