No, moved by one day from 31/3 in 2013 to 30/3 just now.

Windows thinks I'm in (UTC) Dublin, Edinburgh, Lisbon, London, which
is correct.  Windows shows the correct time, as does Cygwin 'date'

Yes, that's how I got the time fixed.  I'm running ntpd from the
Meinberg distribution.

No -- same timezone, we're all in the same city, Edinburgh.  I'm not
aware of anyone else with this problem.

Note that I can't reproduce this anymore :-(.  That is, 32-bit and
64-bit now both require the time to be one hour forward of the correct
time for kinit to work.
