US Daylight Savings Time

Just a note that the US is on Daylight Savings Time now, so our meeting
tomorrow will be one hour earlier (I think) for those in Europe. I think
that means the meeting starts at 3:30 pm UK (GMT+0)?

Or maybe it should be one hour later for us so the meeting starts at the
same time in Europe as it used to? I think Hongchan has a conflict if we
move the meeting to one hour later here.
