Minor Description
There is a mistake in the conversion from UNIX time to FILETIME. See the following page: https://support.microsoft.com/en-us/help/167296/how-to-convert-a-unix-time-t-to-a-win32-filetime-or-systemtime. With the current calculation, checking the properties of a file in a redirected drive/folder gives invalid file dates. Changing the '-' to '+' fixes the issue.
