javascript - Clock on webpage using server and system time? -

i need add together clock web page. clock needs synchronized server don't want have check server page open 24/7 on several pcs. there way time server , utilize systems clock maintain updated , check server every 15 minutes or maintain synced?

the way i've gone before is:

take time server, take time client (immediately) get offset. when showing clock, apply offset current time on client.

you need update server.

the problem you've got sort out though in making request time server, there lag before can client time. can minimize using ajax request server time , nil else, thereby cutting overhead , network lag etc.

javascript ajax vb.net clock clock-synchronization
