How to compare time ignoring seconds.

This one does not directly relates to ActiveSupport , but I thought I put it here since its still relates to Time class.

>> time1,time2 = Time.now,Time.now
=> [Mon Jun 18 10:09:14 -0400 2007, Mon Jun 18 10:09:14 -0400 2007]
>> time1.to_i / 60 > time2.to_i / 60
=> false
>> time1.to_i / 60 == time2.to_i / 60
=> true
