Mismatch between documentation and reality: Valid-Until

[Philipp Kern <pkern@debian.org>]

Hi,

dak and https://wiki.debian.org/RepositoryFormat seem to disagree on the 
definition of the Valid-Until field. dak writes "UTC" as the timezone 
into the Release file, where the repository format references policy 4.4 
but states that it has to be always in UTC. The example given hence 
states "+0000" as the timezone, which is the only timezone specification 
allowed in the trailer of changelog entries. apt pipes it through a 
function that allows more timezones (RFC1123StrToTime), specifically 
GMT/UTC/Z are hardcoded in it. Is there a particular reason why we need 
to allow this if +0000 denotes the same value? Could we at least 
document the field properly? ;-)

I'll also note that policy is slightly ambiguous on how the date is 
supposed to be specified: "dd is a one- or two-digit day of the month 
(01-31)" -- This reads to me as if zero padding is required according to 
the example but not according to the text.

Kind regards and thanks
Philipp Kern
