Question

I have a Problem in my Rails application.

I’ve left everything at standard Rails configuration, so no config.time_zone is set, …

Problem now is:
Given I have a database entry like this:

 c = Client.first
 => #<Client id: 1, short: "Test", last_connected_at: "2011-06-21 09:22:58">

now I generate a Time-Object:

t = Time.zone.parse("2011-06-21 09:22:58")

double check it:

c.last_connected_at
=> Tue, 21 Jun 2011 09:22:58 UTC +00:00
t
=> Tue, 21 Jun 2011 09:22:58 UTC +00:00

So it is identical, but

c.last_connected_at == t => false

Why??? That makes it really hard to find a database row by date.

Thanks a lot for your help.

Answer 1

It’s a caveat. According to the ruby-docs:

All times may have fraction. Be aware of this fact when
comparing times with each other—times that are apparently equal
when displayed may be different when compared.

c.last_connected_at.to_i == t.to_i should work.
