Date substraction returning odd value

I am trying to allow the destruction of a record only if this record has been created within the last 30 minutes.

Then I retrieve the

value of my record (date2) and check against
(date1) :

date1 = 2016-09-21 19:44:52 +0200
date2 = 2016-09-21 17:23:16 UTC

then I just substract the two :


But the result returned is in the 10s of thousands (something like 97000) and increasing very fast when i refresh..(as
changes) whereas we should only get 141 minutes as per above example values


The .minutes is what makes the thing don't work. Remove it and it should work. If you want to find the gap in minutes between to date you just have to substract them, divide the result per 60 and round it.

((date1 - date2) / 60).round

Hope it helped, happy ruby coding!
