ruby on rails - Calculating difference in time between two Time objects -

-

let's create 2 time objects user model:

created = u.created_at updated = u.updated_at

how calculate difference in terms of hours between 2 time objects?

hours = created - updated

i'd wrap in method , extend time class. find hard believe i'd need extend it, can't seem find native method handles calculating elapsed time using different time units.

this should work:

hours = ((created - updated) / 1.hour).round
