This test was made on december 5th 2009:
Time::getMonth() currently returns 11 on Windows (as it is december right now, it obviously should return 12).
In the struct t.tm_yday has a value of 338 but december 5th 2009 is day 339.
This should be corrected.
It would also be nice if it was possible to access the day of the year from a time object as it is calculated anyways, you could just add a function that returns this value. This is currently missing.
