JSP getting local machine time?

Question

I need to create a program which the users are located in two time zone. I will hence need to use the local machine time from their PC to check against certain record in my database. I understand JSP is processed at the server end. Is JSP capable of requesting the local machine time when a user hit the page?
otherwise, is there a way to use javascript to parse the local machine time into JSP?
Thank you.

Answer 1

create a javascript function to get the local time:
function getLocalTime() {
var dDay = new Date();
var nHours = dDay.getHours();
var nMinutes = dDay.getMinutes();
var localTime = nHours + ":" + nMinutes;
document.localTime.value=localTime;
in your jsp include a hidden field to accept the local time:
<input type=hidden name=localTime value="">
call the getLocalTime() function onload, in this way you can get the local time of the client machine when the page is loaded, store it in a hidden field and then retrieve it in the next jsp using request.getParameter("localTime") method.
