This method creates a file and checks the stat to check of an offset between the date on the machine and the created time on the file system. Docker (in my tests) show that you can get the offset using this method.
Once we have the offset, we tell the user (once) and then we use that to find files that have been modified according to the offset (either looking in the last using -mmin or in the future using -newer + a touched file).
