Time system:
In effect, this is "Malkavian Time". We use Greenwich mean time, just because no one ever uses it. All right, and it's base, easily convertible time. Plus, it's non-partisan. Relatively so, anyway.

Converting to Malkavian time:

From:
1. East Coast time (New York City): Add 5 hours.
2. Pacific Time (Los Angeles): Add 8 hours.
3. Hawaiian Time (Honolulu): Add 10 hours.
4. England Time (London): Do nothing. Lucky bastiches.
5. Australian Time 1 (Sydney-Eastern): Subtract 10 hours.
6. Australian Time 2 (Central): Subtract Subtract 9 hours.
7. Australian Time 3 (Western: Subtract 8 hours.
8. New Zealand (Um...dunno any): Subtract 12 hours. That may be 11 hours. I'm not sure...

That annoying daylight savings time: If you have it, you have to subtract one from your conversion to Malkavian time. For example...

Daylight Savings time conversions:
1. East Coast Daylight Savings time: Add 4 hours.
2. Pacific Daylight Savings time: Add 7 hours.
3. Australian Time 1 Daylight Savings time: Subtract 11 hours.

To convert from Greenwich time to your local time, simply reverse it. For example, if you wanted to meet the elusive Hagbutt, who promised to be on at 12 Noon Sunday, Malkavian time, and you were in Pittsburgh (East Coast Daylight Savings time), you would Subtract 4 hours, and realize that you'd have to be on at 8AM in the morning to talk with him.
