How to avoid system date dependency?

Question

I want to break the dependency on the system clock in my application as it can be tampered with. I found this for JAVA. Can anyone point me to something like this or something that helps me achieve this for c++?

Answer 1

You do realize that is just a web call? Someone can tamper with it by doing a man in the middle attack on the web call.

(yes it is harder than just changing the date, but unless you are talking to a secure host it could be intercepted).

I assume you are doing this for some kind of "expire demo code after it has ran for 30 days?" If so, there may be better ways to do that...

Answer 2

You mean something like an NTP Class (this one looks to use boost)? I have not used this one, so ymmv.
