Time zones...

Martin Fowler writes about TimeZoneUncertainty in his bliki. The correctness of his post is shown to me by the minute earlier when I received a Notes originated calendar meeting request from somebody wanting to hold a conference call at 'tomorrow at 3pm (11:00 EST, 8:00 PST)' and the calendar request pops in as 16:00 GMT. Now my local timezone is BST (daylight savings is active) so what is one supposed to do... is the meeting at 15:00 or 16:00 local time.

If we assume that the person sending knows about timezones, then it should be 3.00 pm UTC which becomes 16.00 BST. but what if he meant 15:00 BST and the calendars got it wrong! I know I'll ring him...
