[boost] logging library - minor bug report in "$yy" year formating

Hello there, been playing with the logging library. Is this the right 
place to post bug reports?

It seems that $yy prints "105" for the year 2005, not "05", which I 
expected. $yyyy is correct, it prints 2005.

If line 173,
//    vals[m_yy + 1]       = details.tm_year;
is changed to
//    vals[m_yy + 1]       = details.tm_year % 100;
it appears to work... although I only tested with today's date.
