man Time::Local says

 Whenever possible, use an absolute four digit year instead.

With a detailed explanation about ambiguity of 2-digit years above that.

Please review/test/merge the attached patch (not tested)

This should be addressed. Time::Local's year argument depends on the current year. This will require some tests though, which do not currently exists.

So playing around with apache in a docker container (see #14) seems as though apache always provides a four digit year so I am not sure why we are even ding _guess_year. There is also a new and old format and I think probably only will recognize one of those.

This should be fixed in 6.08_01
