Today I registered myself for an event, a webcast about a technology (making Eclipse pulgins) that will happen in a few days so I want to enter it in my Google Calendar.
The event is slated for starting by January 22, 2008 at 9:00 am PST / 12:00 pm EST / 5:00 pm GMT.
As I'm not in USA the first two time tags are meaningless to me so I'm left with only the third one, namely "5:00 pm GMT". As I'm in Buenos Aires my time id "GMT - 2" during this summer so after some reasoning I think I have to add (or subtract?) 2 hours to the GMT time to get my local time. Or I can visit timeanddate.com and after a while look for Buenos Aires in the long places list to find out that the event will start at 3PM here.
Why didn't I use the timezone option in Google Calendar event details input form?
Well, it happens that there is no such option. Which I think it might be useful for people entering events that will happen somewhere else, for example one that is going to travel.
Actually the screenshot is only a quick and dirty mockup I made for this posting. Just an idea to be developed.
