I've documented the difference in Layout/PatternLayout.pm for now and left the implementation like it was. If people want ISO, they can select that easily.

That's definitely not true, because the code just defines

    } elsif($format eq "ISO8601") {
        $format = "yyyy-MM-dd HH:mm:ss,SSS";

Where did you see evidence in the documentation that predefined formats are faster? I'd like to correct that if that's in there.

I've thrown out all the 'YYYY' leftovers now. 'yyyy' is the correct way.

Let me know if I've overlooked anything ...

Sorry for creating this confusion. It's my typo. I was thinking log4j 
but writing log4perl. The *log4j* docs claims that the standard formats 
are much
faster.
