This is a shortcoming in Cygwin itself.  You can only workaround it
by setting the date from a Cygwin process for now.  This will only
affect Cygwin processes running in the same user session, though.
There's a TODO in the affected code in Cygwin which describes this
very problem.  Unfortunately this requires a redesign of the code
in question...
