Clock on webpage using server and system time?

Question

I need to add a clock to a web page. The clock needs to be synchronized with a server but I really don\'t want to have it constantly check the server as the page will be ope

Answer 1

You can get the current time from the server on every page load, so even on first load you will have the current server time. After that, you may use a javascript timer on the page set to tick every second, and then you will virtually have a clock working synchronized with the server. You may also try applying offsets as suggested, but i wouldn't recommend since there's lag during postbacks.

Ajax request might be an interesting option.

Any doubts, you may also check this clock out!

Also, W3Schools is a great reference for javascript.
