[GLLUG] Squid thinks time is an hour in the past

[Tim Woodall]

Found it - I needed:
refresh_pattern ^http://aptmirror17.home.woodall.me.uk/ 0 0% 0 refresh-ims

in my squid.conf.

I still don't understand why the times seem to be an hour out but that
wasn't the source of my problem after all.

Tim.
