Date object from server

[Ike]

Is there a way to obtaiun a date object from a server in an applet (I want
it to meake certain the user's clock on their local machine isn't set to a
date more than 24 hours away from this). Thanks, Ike

yes

..(I want it to meake certain the user's clock
on their local machine isn't set to a

Thanks, Ike

No worries,..

Yes Andrew, but I believe this is Windows-dependent (uses JNI down under the
hood). Thanks anyhow though -Ike

Have a look at http://mindprod.com/jgloss/setclock.html


It is overkill for what you want to do using atomic clocks.

If you can run a servlet on the server, it is trivial. Just return a
long timestamp.

SetClock does use JNI to SET the user's clock, but it uses only
vanilla Java to find out the precise time.

It is quite a production. You might canibalise just the part that
sends a datagram to a time server and gets one back.

11,265 pcclock.jar -- native DLL for setting the clock
20,539 setclock.jar -- Java for getting the time and displaying it a
running display.
