Email server - incorrect clock.

[#1]

Incoming emails are sometimes showing a 'received' time 30 minutes before they are sent.
Seems to be a problem with  ... fhw-inmx16.plus.net with esmtp (PlusNet MXCore v2.00) id ....

I suppose that it is time to call support, as this is still happening:
One just arrived (from the ccgi server - a PHP form of mine) with the header (only part shown):

As you can see, it was delivered 20 minutes before it was sent (eat your heart out Einstein).
Spoke to CS at 20:17

The naming convention in bold stands for Field House Way which is the data centre we had problems with the other day. This was actually noticed by somebody posting in Usenet last night and I raised it this morning. Doesn't look like anybody has had the chance to pick it up though
The timezone and NTP needs checking on the servers.

@Bob - Yes looking back, the earliest email that arrived before it was sent was at 1pm Thursday.
I run a support desk and the emails are displayed in the wrong order in the inbox.
I was informed by CS that networks do not work at weekends, so it will probably be Monday before the clock is adjusted.

I'd be inclined to agree with that, I did mention it again to the on-call engineer last night but as it's not likely to be having a huge impact on customers then it may not get sorted until Monday.

This should now be fixed.
