I don't think this is a Subversion bug, because it doesn't call
GetTickCount() anywhere at all. I think it is more likely a bug in
Cygwin's "unix translation" layer. My suspicion is that Subversion
calls the APR time functions to get the current system time, then APR
calls the standard unix time functions, and then Cygwin translates the
unix call into a windows GetTickCount().

How about this: don't run an svn server under cygwin. There's
absolutely no reason to use cygwins hack-y "translation" layer when
true, 100% native windows binaries are available. Sure, cygwin is
generally convenient, and so is the 'native' cygwin svn client. But
for something as important as a server process, I wouldn't trust
cygwin any farther than I can throw it.
