[squid-users] false skew

I have an odd situation where I'm getting
reports of 'clock skew' when retrieving
certain files. The last modified time in
the header is correct, but the 'Date'
field does not appear to be meaningful.
The time on the content server is exactly
GMT+2 (CEST) as is the time on the squid
servers which are reporting this (there
are 3) ie. there is *no* skew at all.

For a file retrieved at 08:21 GMT today
(10:21 localtime) it reports:

Date: Thu, 26 Jul 2001 17:14:10 GMT

Where is this bizarre time coming from?

thanks,
Mike
