各地时间显示

时间各地时间显示

下面为效果显示

脚本说明:
第一步：把如下代码加入<body>区域中
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var timerID ;
function tzone(tz, os, ds, cl)
{
	this.ct = new Date(0) ;		// datetime
	this.tz = tz ;		// code
	this.os = os ;		// GMT offset
	this.ds = ds ;		// has daylight savings
	this.cl = cl ;		// font color
}
function UpdateClocks()
{	
	var ct = new Array(
		new tzone('SFO: ', -8, 1, 'lime'),
		new tzone('TYO: ', +9, 0, 'violet'),
		new tzone('HKG: ', +8, 0, 'cyan'),
		new tzone('BKK: ', +7, 0, 'yellow'),
		new tzone('NYC: ', -5, 1, '#FFAA00'),
		new tzone('LON: ',  0, 1, 'silver'),
		new tzone('SVO: ', +3, 0, 'pink'),
		new tzone('KTM: ', +5.75, 0, 'red')
	) ;
	var dt = new Date() ;	// [GMT] time according to machine clock
	var startDST = new Date(dt.getFullYear(), 3, 1) ;
	while (startDST.getDay() != 0)
		startDST.setDate(startDST.getDate() + 1) ;
	var endDST = new Date(dt.getFullYear(), 9, 31) ;
	while (endDST.getDay() != 0)
		endDST.setDate(endDST.getDate() - 1) ;
	var ds_active ;		// DS currently active
	if (startDST < dt && dt < endDST)
		ds_active = 1 ;
	else
		ds_active = 0 ;
	// Adjust each clock offset if that clock has DS and in DS.
	for(n=0 ; n<ct.length ; n++)
		if (ct[n].ds == 1 && ds_active == 1) ct[n].os++ ;
	// compensate time zones
	gmdt = new Date() ;
	for (n=0 ; n<ct.length ; n++)
		ct[n].ct = new Date(gmdt.getTime() + ct[n].os * 3600 * 1000) ;
	document.all.Clock0.innerHTML =
		'<font color="' + ct[0].cl + '">' + ct[0].tz + ClockString(ct[0].ct) + '</font>' ;
	document.all.Clock1.innerHTML =

	document.all.Clock2.innerHTML =

	document.all.Clock3.innerHTML =
		'<font color="' + ct[3].cl + '">' + ct[3].tz + ClockString(ct[3].ct) + '</font>' ;
	document.all.Clock4.innerHTML =
		'<font color="' + ct[4].cl + '">' + ct[4].tz + ClockString(ct[4].ct) + '</font>' ;
	document.all.Clock5.innerHTML =

	document.all.Clock6.innerHTML =
		'<font color="' + ct[6].cl + '">' + ct[6].tz + ClockString(ct[6].ct) + '</font>' ;
	document.all.Clock7.innerHTML =
		'<font color="' + ct[7].cl + '">' + ct[7].tz + ClockString(ct[7].ct) + '</font>' ;
	timerID = window.setTimeout("UpdateClocks()", 1001) ;
}
function ClockString(dt)
{
var stemp, ampm ;
	var dt_year = dt.getUTCFullYear() ;
	var dt_month = dt.getUTCMonth() + 1 ;
	var dt_day = dt.getUTCDate() ;

var dt_hour = dt.getUTCHours() ;

var dt_minute = dt.getUTCMinutes() ;

var dt_second = dt.getUTCSeconds() ;

dt_year = dt_year.toString() ;

if (0 <= dt_hour && dt_hour < 12)

{

ampm = 'AM' ;

if (dt_hour == 0) dt_hour = 12 ;

} else {

ampm = 'PM' ;

dt_hour = dt_hour - 12 ;

if (dt_hour == 0) dt_hour = 12 ;

}

if (dt_minute < 10)

dt_minute = '0' + dt_minute ;

if (dt_second < 10)

dt_second = '0' + dt_second ;

stemp = dt_month + '/' + dt_day + '/' + dt_year.substr(2,2) ;

stemp = stemp + ' ' + dt_hour + ":" + dt_minute + ":" + dt_second + ' ' + ampm ;

return stemp ;
}
//  End -->
</script>

第二步：把<body>中的内容改为：
<body  onLoad="UpdateClocks()">
