Hi,

According to http://httpd.apache.org/docs/current/mod/mod_log_config.html#formats (see '%t' documentation) and http://httpd.apache.org/docs/current/logs.html#common, the output should be "10/Dec/2010" (with no accents, even with my french environment).

So, i think the CoreConstants.CLF_DATE_PATTERN should be "dd/MMM/yyyy:HH:mm:ss Z"; and the SimpleDateFormat should be instantiated with Locale.EN_US or Locale.ENGLISH for the %t default case.

Regards
