Javascript Date Library that uses online API? Rather than client machine? : I'm writing a node.js package that I want to distribute. I want a function to run at a certain time... but I don't want to use any of the popular JS libraries because they use the client's machine to determine date - rather I don't want this to be alterable. 

Basically the script should break after a certain date and should not be able to be reverse by changing your PC's time. Is this possible?

P.S. I have no desire to create another server to serve this date. But that's the outcome I want to achieve.
