That diagram oversimplifies, in that it ignores daylight saving time. You really need two charts, one for northern summer/southern winter, and vice versa.
Second, we really want that chart weighted by number of Moodle developers (or potential Moodle developers) in each time zone.
At the extremes, for California the meeting was 06:00 to 08:00, which is probably on the boundaries of tolerable. (There are Moodlers in Alaska)
For New Zealand, it was 01:00 to 03:00. That is really very unpleasant.
