syncronize time

[Kaisen2100]

Anyone knows how to syncronize the actual time/date with a server like windows do with "time.windows.com"

Thanks ... this info is usefull to make a verification of a registration key ...
the idea is to generate Reg Keys with some a "valid until DD/MM/YY" (this info encrypted in any way) so when the user enter the Reg Key the program connect to the server to verify if the user's date is right ... and if the Key is valid yet ... then you activate the program.

You can use it with the user's computer date but, the user can modify the date to make the Reg Key valid ... so if you check it against a server like the
NIST server http://tf.nist.gov/timefreq/index.html there is no way to have alter the date ... if the date in the server is ok then you activate the Program ... it is something like Registration and Product Activation at the same time.

what you think about it?
