Short reminder: From today, for a week, Europe is already on winter time, while the US are still on Daylight Saving Time (DST).

So if you have recurring appointments with people from the other continent: European appointments will be 1 hour later for US folks, and US appointments will be *one hour earlier* for Europeans.

@uliwitness just a tip for those scheduling international meetings: also specify the time in UTC.
@doc Doesn't help recurring meetings, where people often don't even check their calendar anymore, and suddenly it’s moved by 1 hour, or meetings at the start of the day, where people might be on the road when they realize the meeting is now, not in 1 hour.
