[erlang-questions] Print Date

[Thomas Lindgren]

Here's my honest advice to the guy who has been sending us his homework: For these kinds of problems, ask your tutor. 

And as a bonus, here's something that may help homework guy out, hopefully before he will be inflicted on the world as a contractor: http://catb.org/~esr/faqs/smart-questions.html

Best,

Thomas
