Trying to trick birth date

1

i was trying to trick this forum’s birth date (sorry) by entering year 2010 or something, so at the main forum, it would show a negative age. i almost knew i wouldn’t succeed, because they wouldn’t be that dumb not to code for wrong year’s input. but i got close. take a look at the picture attached. uhm humm, sorry, but i wanted to check this out, if they coded it right :huh:
