On windows 7 you can add clock that shows Pacific time. This is the time ArenaNet seems to use for all event announcements, so we will need this also in future.
How to:
On Windows 7, click on your clock and click “Adjust time/date”, click the “Additional Clocks” tab, check “Show this clock” on one of the additional clocks, set it to “(UTC-08:00) Pacific Time (US & Canada)”, and give it a name like “ArenaNet” or whatever. This will show you a clock that shows you Pacific time to remind you of the time difference between your time and ArenaNet’s whenever you click on or hover over your clock.
