Changing the Varnish Date header to UTC

Hi all -

Hopefully a quick one - Is there any way to get varnish to provide the date
header in UTC instead of GMT?

That's OS being retarded, Varnish sets its TZ variable to "UTC".

No, it's the required format according to RFC2616. See section 3.3.1:

HTTP-date = rfc1123-date | rfc850-date | asctime-date
rfc1123-date = wkday "," SP date1 SP time SP "GMT"
rfc850-date = weekday "," SP date2 SP time SP "GMT"
