Bug#441422: apt: looses modification time data of *Translation* files
Package: apt
Version: 0.7.6
Severity: important
Short story: apt redownloads _old_ files via HTTP while it should track
the date like it does with some other periodically updated files.
And there is some real problem, watch out for Last-Modified,
If-Modified-Since and file storage times. What actually happens is that
decompressed files do not have the right modification date, instead they
get a totally wrong date (we don't have May 16 2006 now). And this one
is later used for If-Modified-Since/If-Range fields.
