I experienced that a couple years ago, left Ontario airport at 3:15 and arrived in Arizona at 3:20 (something like that) Took me a while to realize it was not an error on the ticket, but the time change (duhh)
Probably would have been the other way around. You leave here and get there at the same time. Ontario to Phoenix is a 2 hour flight. Phoenix to Ontario takes no time at all.
