I believe that you are correct. I am in the Eastern time zone and 12 am UTC is 8 PM here and the Pacific time zone where both of you are is 3 hours off from the Eastern time zone. This is of course going to change soon in early November when Daylight Savings Time ends. (in the US at least, I don't know about Canada.) After that 12 am UTC will be 7 PM Eastern.
