Copy Code code as follows:

Y: "Years"
M: "Months"
W: "Weeks"
D: "Days"
D: "Totaldays"

H: "Hours"
M: "Minutes"
S: "Seconds"

2, display format: Distance end time also: 00 days 05 hours 25 minutes 30 seconds (seconds for running seconds)

Copy Code code as follows:

<div id= "Time" class= "Time" ></div>
<script language=javascript>
function Show_date_time () {
Window.settimeout ("Show_date_time ()", 1000);
Target=new Date (2014,0,15,17,0,0); Note: The parameters that represent the month are between 0 and 11. In other words, if you want to set the month to August, the argument should be 7.
Today=new Date ();

Timeold= (Target.gettime ()-today.gettime ());

sectimeold=timeold/1000
Secondsold=math.floor (Sectimeold);
msperday=24*60*60*1000
E_daysold=timeold/msperday
Daysold=math.floor (E_daysold);
E_hrsold= (e_daysold-daysold) *24;
Hrsold=math.floor (E_hrsold);
E_minsold= (e_hrsold-hrsold) *60;
Minsold=math.floor ((e_hrsold-hrsold) *60);
Seconds=math.floor ((e_minsold-minsold) *60);

if (daysold<0) {
document.getElementById ("Time"). Innerhtml= "Overdue, the countdown has expired";
}
else{
if (daysold<10) {daysold= "0" +daysold}
if (hrsold<10) {hrsold= "0" +hrsold}
if (minsold<10) {minsold= "0" +minsold}
if (seconds<10) {seconds= "0" +seconds}
if (daysold>0) {
document.getElementById ("Time"). Innerhtml= "The distance is also:" +daysold+ "Days" +hrsold+ "hours" +minsold+ "minutes" +seconds+ "seconds";
}
Else
document.getElementById ("Time"). Innerhtml= "<font color=red> distance End times also:" +daysold+ "Day" +hrsold+ "hours" +minsold+ "points"  +seconds+ "SEC </font>"; End time is less than 1 days, the font is red alert
}
}
Show_date_time ();
</script>

3, display format: has been running 0 years 1 days 0 hours 4 minutes 35 seconds (seconds for running seconds)

Copy Code code as follows:

<span id= "Sitetime" ></span>
<script language=javascript>
function Sitetime () {
Window.settimeout ("Sitetime ()", 1000);
var seconds = 1000
var minutes = seconds * 60
var hours = minutes * 60
var days = hours * 24
var years = days * 365

var today = new Date ()
var todayyear = Today.getfullyear ()
var todaymonth = Today.getmonth ()
var todaydate = Today.getdate ()
var todayhour = today.gethours ()
var todayminute = today.getminutes ()
var todaysecond = Today.getseconds ()

/* DATE.UTC ()--Returns the number of milliseconds (timestamp) between midnight of the Date object from World Standard Time (UTC) January 1, 1970
Year-years as Date object, 4-bit year value
Integer between month-0-11, as the month of the date object
Integer between day-1-31, number of days as Date object
Hours-0 (24 O'Clock Midnight)-an integer between 23, the number of hours as the date object
Integer between minutes-0-59, number of minutes as Date object
The integer between seconds-0-59, the number of seconds as the date object
The integer between microseconds-0-999, the number of milliseconds to be the date object.
var T1 = DATE.UTC (2014,0,14,11,19,00)
var t2 = DATE.UTC (Todayyear,todaymonth,todaydate,todayhour,todayminute,todaysecond)
var diff = T2-t1

var diffyears = Math.floor (diff/years)
var diffdays = Math.floor ((diff/days)-diffyears*365)
var diffhours = Math.floor ((diff-(diffyears*365+diffdays) *days)/hours)

}
