Comment 5 for bug 331094

Ok, for all the cases I've investigated (above examples by Martin Pitt for lv.po and ro.po), this is the situation:
 * There was no file upstream imported
 * One gets created (eg. 2007-04-20 19:29+0300 for lv.po; 2008-09-21 23:42+0300 for ro.po from packages)
 * Before that one gets imported, a file in LP is created (2007-04-21 09:38+0300 for lv.po, 2009-02-12 12:22+0200 for ro.po).
 * This causes imported file to be considered as older (i.e. 2007-04-20 vs. 2007-04-21, and 2008-09-21 vs. 2009-02-12).

Solution should be simple: do not check for PO revision date on published imports. Of course, we need to think about what problems will this cause?
