That may be the dumbest copy-protection scheme I've ever seen! What's to stop the client from editing just one line of your routine to read:

return 1; #renew your license - NOT!

Or better yet, just edit out the call to the subroutine in the first place!

    Perhaps you did not uderstand me.
    It's just dummy code that gives an idea of what you could do, returning either 1 or 0 is just a boolean expression or calling it as a sub is just to help me explain what i ment to do, this is not a final solution, just an idea on how you could do something like this. How you implement it in your code is up to the programmer.

    The thing i ment to do, is showing a way to use dates to see if you've got a valid license, not the implementation itself.

    Anyway, using a license code is not an ideal idea anyway (as i said before), it allways can be hacked out. The OP however did ask not to be 100% safe on hidding source, just make it more difficult.

    The idea of calling for certin functions to your own server is a bad idea as well, it's not failsafe. It however gives fresh ideas to the OP so he can think of a proper solution to his problem.
