Precise date calculation for stdWrap.age
There's an issue when calculating in years because it presumes that a year has always 365 days, more details can be read here:
A suggestion from Phillip Gampe:
... should refactor the method to use DateTime->diff(), which should be accurate, but does only exists for PHP 5.3. Thus it cannot go into 4.5.
I would even suggest that you turn this "bug" into a TASK and we submit this only to 6.2 with the subject "Precise date calculation for stdWrap.age". This should be covered with unit tests of course (which in this case a really simple, because we do not need mocking).
