Get current date/time in seconds

Question

How do I get the current date/time in seconds in Javascript?

Answer 1

You can met another way to get time in seconds/milliseconds since 1 Jan 1970:

var milliseconds = +new Date;        
var seconds = milliseconds / 1000;

But be careful with such approach, cause it might be tricky to read and understand it.

Answer 2

To get today's total seconds of the day:

getTodaysTotalSeconds(){
    let date = new Date();        
    return +(date.getHours() * 60 * 60) + (date.getMinutes() * 60) + date.getSeconds();
}

I have add + in return which return in int. This may help to other developers. :)

Answer 3

Date.now()-Math.floor(Date.now()/1000/60/60/24)*24*60*60*1000

This should give you the milliseconds from the beginning of the day.

(Date.now()-Math.floor(Date.now()/1000/60/60/24)*24*60*60*1000)/1000

This should give you seconds.

(Date.now()-(Date.now()/1000/60/60/24|0)*24*60*60*1000)/1000

Same as previous except uses a bitwise operator to floor the amount of days.

Answer 4

I use this:

Math.round(Date.now() / 1000)

No need for new object creation (see doc Date.now())

Answer 5

var seconds = new Date().getTime() / 1000;

....will give you the seconds since midnight, 1 Jan 1970

Answer 6

To get the number of seconds from the Javascript epoch use:

date = new Date();
milliseconds = date.getTime();
seconds = milliseconds / 1000;
