Actually I am still waiting for support to revert to me on one of my queries about faceman date/time being out.
If one of the server's date/time can be off by a few weeks, it doesn't give me any assurance that the time on the headers are correct.
It is quite pointless to examine the headers if the date/time stamp are incorrect.
