I've just implemented a simple method to store the timestamp in the
clipboard data itself.  Since there's no way to modify stored data, only
one timestamp is stored and then used as modification and access time.
This only works within Cygwin.  If you change the clipboard from outside
Cygwin, the timestamps will be very likely reset because the
Cygwin-specific clipboard data will be deleted, so this is not reliable.
The problem is that the clipboard is window station specific and there's
no way to store window station specific, persistent data somewhere else.
