Hockey and Time Zones

This probably isn't interesting to anyone else, but the Avalanche play evening games this year that from the perspective of the Eastern time zone, start at 7pm, 7:30, 8, 8:30, 9, 9:30, 10 and 10:30.

Eastern is what's listed on the ESPN schedule, but I thought it would be interesting to break it down with local time, and Mountain time.

Notes
Local time is fairly consistent. Usually 7 or 7:30, with some occasional 6pm and 8pm games in Denver in the mix too. Mountain time varies from 5pm to 8:30. I prefer a start time of either 6 or 7pm, Mountain Time.
