Tips for extracting only a portion of the JavaScript timestamp

I have a JavaScript timestamp that reads 

Tue Sep 30 2014 12:02:50 GMT-0400 (EDT)
.

When I use the .getTime() method, I get 1412092970.768

Typically, this timestamp represents a specific time of today. My question is whether it's possible to extract only the day, month, and year while keeping the hour, minute, and second values at 0.

For our current scenario, the desired format would be 

Tue Sep 30 2014 00:00:00 GMT-0400 (EDT)
.

I'm unsure about how to go about this conversion process. Converting to Unix timestamp using getTime() doesn't seem to provide clear instructions, and I am unable to set the time directly like in PHP.

Is there a solution to rectify this issue?

Thank you

Answer №1

To manipulate a date object, you can initialize it and then reset any unwanted components to zero or specify the desired components, for example:

date = new Date();
date.setHours(0);
date.setMinutes(0);

Alternatively, you can do something like this:

date = new Date(); // current date and time

newDate = new Date(date.getFullYear(), date.getMonth(), date.getDate(), 0 , 0, 0, 0);
// create a new date with only year/month/day values and time set to zero.

For more information on the constructor's arguments, refer to: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date

Answer №2

Another approach would be to pass the epoch value to PHP:

JS:

let currentEpoch = Math.floor(Date.now() / 1000);

PHP:

$epochTimestamp = strtotime("@$currentEpoch");
echo date('Y', $epochTimestamp); //year
