The timestamps you get from stat() are just the current system time, converted into a file time. This can result in conversion inaccuracy, apparently. Nothing we can do against for the current release. Remove the check against /dev/null or convert it to a check against some other random file. I'm wondering what this is supposed to do anyway. In the long run, maybe it would be better in Cygwin to set the timestamp for devices to epoch.
