Client Dempsey living in one of an East Coast state of the U.S was taking to Landon Donovan, who was living in the West Coast state of the U.S.

Dempsey: What time is it?
Donovan: Wow, It is the same time here.

How is this possible?

The conversation taking place in DST when there is a gap of approx 1hour in one of the city.
