Description of problem:
The dates in /var/log/yum.log are in dd/dd/dddd (where d is a digit)
format. Unfortunately yum does not appear to have localised this date
and consequently the dates look a little strange for a machine in the UK.

Version-Release number of selected component (if applicable):
yum-2.0.7-1.1

How reproducible:
Always

Steps to Reproduce:
1. less /var/log/yum.log

Actual Results:  ...

(the middle "month" digits are changing too fast)

Although lacking the year, this format is typical of other log files
and is unambiguous so you do not need to match the locale etc.
