Bug#504106: etc/cron.daily/apt gives an error on daylight saving change

[Maximiliano Curia <maxy@gnuservers.com.ar>]

Package: apt
Version: 0.7.16+b1
Severity: minor

Hi,

etc/cron.daily/apt uses:
date --date=$(date --iso-8601) %s
which fails for dates where the daylight saving occour, as the 00:00:00 for
that date doesn't exists. For example:
Argentina/Buenos_Aires changed its time the 2008-10-19 from 00:00:00 ART to
01:00:00 ARST so, issuing:
TZ=America/Argentina/Buenos_Aires date --date="2008-10-19" gives an error:
 date: invalid date «2008-10-19»

Which is correct, as there was no "2008-10-19 0:00:00" ART or ARST

A simple solution could be to add export TZ=UTC at the begining of the file.

Thanks,
