Estimated Drift:

This javascript application takes 100 measurements of the current time from my web server and compares it to your local time and calculates how much your local clock is different. It also removes any network and processing time delay from the calculation. This is also mitigated by the 100 iterations. This is by no means close to or better than NTP (Network Time Protocol) but it can get you close.
