rsync - Apr 2002 - is it a bug or a feature? re:time zone differences, laptops, and suggestion for a new option

I just did a win2k install, and as I thought i'd remembered, it asked 
whether the hardware clock was UTC or localtime (and recommends 
localtime).  Of course, I chose UTC, but most would probably follow 
MegaSloth's recommendation.  I don't know how to change it on an 
already-installed system, though.  Does anyone else?

Melbourne just went off daylight savings.  I reckon there's a
connection there.  :-)

Microsoft like storing the local time in the hardware clock, which is
not the smartest design in the world.  They have to kludge it when the
timezone's offset changes; this is particularly problematic on
laptops, and also if you dual-boot the machine either between unix and
xp, or different M$ installations.

A patch to fix that will go into 2.6.

Lapo, how do you handle this for the Cygwin build?

Thanks,
