Is it just me or does “changing the clocks” bring a cloud of problems with time? Not only have I adjusted the time on my computer several times, but the real chaos happens with calendar invitations. I still haven’t fully figured out the reasons, but it seems that problems arise when the invitee and the inviter have different time zones (UTC+4 and UTC+3) but the same time (the first one changed the time zone, the second moved the clocks, so eventually both have the same time). Mail programs and calendars see that the time zones are different and perform the conversion themselves. As a result, you invite someone for 12:00, but they receive a completely different time in their email and on their calendar.
