Comparing identical DateTime objects in ruby — why are these two DateTime.now's not equal?

Question

In a rails app, I have model code of the form:

def do_stuff(resource)
  models = Model.where(resource: resource)
  operated_at = DateTime.now

  models.each         


        

Answer 1

DateTime.now doesn't work for comparison with Database datetime object.

Example:

1. If you have the server running in Pacific Time Zone, you will expect to get the

   DateTime.now --> Fri, 25 Oct 2013 15:28:21 -0800

(Daylight Saving Time in October supposed to be -7 hour from UTC, but somehow the datetime.now always give you -8 from UTC)

1. I think if you use Time.zone.now instead of DateTime.now will give you the correct comparison.

   Time.zone.now --> Fri, 25 Oct 2013 15:27:17 PDT -07:00
