Make the server's clock available to the browser.
You can use it when you want to display the current time but don't trust the browser's clock to be accurate, or to synchronize events for different users of your web site by synching them all to the server's clock.
Usage is simple. Add one
<SCRIPT> element to your web page and then you can
object, except that it reflects the server's time instead of the client's.
ServerDate has been tested in the following browsers:
Include the following
<SCRIPT> element in your web page:
You may then use
ServerDate as you would use the
Date object or one of its
> ServerDate"Mon Aug 13 2012 20:26:34 GMT-0300 (ART)"> ServerDatenow1344900478753> ServerDategetMilliseconds22
There is also a new method to get the precision of ServerDate's estimate of the server's clock (in milliseconds):
> ServerDatetoLocaleString + " ± " + ServerDategetPrecision + " ms""Tue Aug 14 01:01:49 2012 ± 108 ms"
You can see the difference between the server's clock and the browsers clock, in milliseconds:
> ServerDate -39
There is no constructor because it doesn't make sense to create more than one
Date to change the time, such as
setMinutes, are not defined:
ServerDate is synchronized with the server's clock when it is first loaded and
then re-synchronizes itself from time to time to keep the two clocks from
