Doing sums with Time objects will give you an int or float, representing
seconds. You can then divide that by 86400 to get the time in days. If
you get a float back, and just want whole days, then just call .to_i or
'round' on it.
eg
puts "Created about #{((yourhash[:date_last_updated] -
yourhash[:date_created])/86400).round } days ago"
If you want it in days and hours, that's a bit more longwinded but you
could write a method to do it.
It always seemed to me that Ruby is missing a 'duration' class that
represents the difference between two times, with nice methods for
displaying the difference in hours, days, months, years etc. Is there
one and i missed it?
