我有两个日期YYYY-MM-DD和ZZZZ-NN-EE
我怎么知道它们之间有多少秒呢?

在bash中:
bc <<< "$(date --date='1 week ago' +%s) - \
$(date --date='Sun, 29 Feb 2004 16:21:42 -0800' +%s)"
它确实需要安装bc和gnu日期。

简单的方法:
function diff_hours(dt2, dt1)
{
var diff =(dt2.getTime() - dt1.getTime()) / 1000;
diff /= (60 * 60);
return Math.abs(Math.round(diff));
}
function diff_minutes(dt2, dt1)
{
var diff =(dt2.getTime() - dt1.getTime()) / 1000;
diff /= (60);
return Math.abs(Math.round(diff));
}
function diff_seconds(dt2, dt1)
{
var diff =(dt2.getTime() - dt1.getTime()) / 1000;
return Math.abs(Math.round(diff));
}
function diff_miliseconds(dt2, dt1)
{
var diff =(dt2.getTime() - dt1.getTime());
return Math.abs(Math.round(diff));
}
dt1 = new Date(2014,10,2);
dt2 = new Date(2014,10,3);
console.log(diff_hours(dt1, dt2));
dt1 = new Date("October 13, 2014 08:11:00");
dt2 = new Date("October 14, 2014 11:13:00");
console.log(diff_hours(dt1, dt2));
console.log(diff_minutes(dt1, dt2));
console.log(diff_seconds(dt1, dt2));
console.log(diff_miliseconds(dt1, dt2));
在bash中:
bc <<< "$(date --date='1 week ago' +%s) - \
$(date --date='Sun, 29 Feb 2004 16:21:42 -0800' +%s)"
它确实需要安装bc和gnu日期。
减:
var a = new Date(); 警报(“等待几秒钟,然后点击确定”); var b = new Date(); Var差= (b - a) / 1000; console.log("You waiting: " + difference + " seconds");
var a = new Date("2010 jan 10"),
b = new Date("2010 jan 9");
alert(
a + "\n" +
b + "\n" +
"Difference: " + ((+a - +b) / 1000)
);
你可以简单地做。
var secondBetweenTwoDate = Math.abs((new Date().getTime() - oldDate.getTime()) / 1000);
