I used this to calculate the difference between server time and the users local time. Grab the hour difference and drop that in a form when the user is registering. I then use it to update the time on the site for the user when they do stuff online.

Once I got it working, I switched this line ...

if (form.date1.value == "")
    form.date1.value = s;

to ...

    form.date1.value = "";

Now I can compare the user time and the server time! You can grab the seconds and mins as well.
