How to coordinate the clock when dual-booting with Windows

I'm totally biased, having a long standing hatred for time zones... I
work in a job where there are at least five different timezones in use
all day, every day, and they are always a pain.   I work with a guy
trouble tracking issues, and the same system reports all times in his
timezone, and to me in my timezone (3 hours different.) while the
systems we are running together (for sanity) are all in UTC, it is
very, very confusing.

Sample bug... we download data from an ftp server that is in their
local time zone.  We need to pick out the new files that showed up in
a tree since the last time we looked (we look every few minutes.)   we
basically store the result of each listing in a file, and diff it.

Every six months, All of the files in the tree change, because the
operating system reports a different date for the same file than it
did an hour before... many thousands of files, and then they get
processed... yes we can write vastly more complicated logic to work
around this, but diffing files just won't work... twice a year.

yes, seething hatred...
