# Difference in minutes betwen two Datetime

Hi!

I need to calculate the difference between two Datetime and convert it
into minutes.

diff = Time.now() - my_date

How can I convert diff now into minutes?

Best regards

What class is my_date ? (my_date.class)
Is it DateTime, or is TIme or ActiveSupport::TimeWithZone ?
In general, the difference seems to be in seconds when you subtract
two objects of the same class so you'd divide by 60 to get minutes. I
think you can also subtract between Time and TimeWithZone but you may
run into trouble with other combinations.

why you don't use distance_of_time_in_words()?

you can rewrite maybe this method in a helper and customize.

It returns the difference in a hash

ruby-1.8.7-p302 > t1 = Time.now
=> Wed Mar 09 16:24:09 +0000 2011
ruby-1.8.7-p302 > t2 = Time.now
=> Wed Mar 09 16:24:22 +0000 2011
ruby-1.8.7-p302 > t2 - t1
=> 12.607967

The difference is in seconds. I think your my_date variable is not a
Time or DateTime object.
