You can use available methods to get the time in past or future using ago, since alias for from_now and many available methods

Time.current
#=> Tue, 20 Sep 2016 15:03:30 UTC +00:00

2.minutes.ago
#=> Tue, 20 Sep 2016 15:01:30 UTC +00:00

2.minutes.since
#=> Tue, 20 Sep 2016 15:05:30 UTC +00:00 

1.month.ago
#=> Sat, 20 Aug 2016 15:03:30 UTC +00:00

1.year.since
#=> Wed, 20 Sep 2017 15:03:30 UTC +00:00
