*grins* Oh boy, time conversions are always a can of worms! The group I play with in Ultima Online has this same problem every single month when we have our major event.
Here's basically how things work.
EST is UTC/GMT -0500. When it's 1200GMT it's 0700EST. Pretty straightforward. Now where things get screwy is in April when North America, Europe and Russia (according to
World Time Zone) go onto Daylight Savings Time. They all jump ahead one hour, but UTC/GMT stays the same. This means London is now GMT+0100 and EDT (note the D instead of the S) is GMT-0400. So while the US gains an hour on UTC/GMT, we don't gain an hour on Europe itself. (by the way, last I heard, Arizona doesn't observe daylight savings, so they're always Mountain Standard)
A possible solution to the time problem is to post either the UTC time of the event. Also, make sure that you use EDT when we're in daylight savings for the people in areas that don't observe daylight savings, or they might be an hour late for the event!
Daddog, I had loads of fun yesterday in the scenario flying with the Mongrels!!!
Good work on the scenario, just wish we coulda had more people. Ya should talk to Ripsnort, there were a lot of 323 on when I went to the MA after the Chk 6! I've seen him talk about wanting to fly over historical terrains.
