Code review comment for lp:~jpds/launchpad/timestamp-archivepublisher-run

= Summary =

The archivepublisher does not timestamp its trace files, it just touch'es the file. Mean while most of our mirrors timestamp when they synced with 'date -u' in their trace files:

This branch changes this behaviour to mimic that of the mirrors.
