Obtain the GMT date for the next day

Question

Obtain the GMT date for the next day

Need help with code to get the current date and the current date + 1 day (in GMT).

var now = new Date();
var newexp = (now + 3);
var show = newexp.getGMTString();

alert(show);

Goal is to set a cookie to expire in 1 day.

function SetCookie(name, value, exp) {
 var now = new Date();
 var newexp = (now + exp); // exp being # of days before expiration
 document.cookie= name + "=" + value+ "; expires=" + newexp.getGMTString() + ";"
}

SetCookie('name', 'john', '3');

Having issues with the code, need assistance.

The Date object in Javascript allows for simple manipulation of dates stored within it.

To retrieve a Date object for the following day, you can use the following code:

var date = new Date();
date.setDate(date.getDate() + 1);

function UpdateCookie(name, value, exp) {
var current = new Date();
current.setTime(current.getTime()+(exp*24*60*60*1000));
document.cookie= name + "=" + value + "; expires=" + current.toGMTString() + ";"
}

UpdateCookie('name', 'john', '3');

Revised the function to use 'exp' as the factor which represents the number of days for the cookie's expiration.

Answer 4

function UpdateCookie(name, value, exp) {
var current = new Date();
current.setTime(current.getTime()+(exp*24*60*60*1000));
document.cookie= name + "=" + value + "; expires=" + current.toGMTString() + ";"
}

UpdateCookie('name', 'john', '3');

Revised the function to use 'exp' as the factor which represents the number of days for the cookie's expiration.

Consider looking at it from a different perspective by going back to the basic "number of milliseconds since the epoch" concept:

var currentDate = new Date()
currentDate.setTime(currentDate.getTime() + 24 * 60 * 60 * 1000)

Alternatively, you can use two separate variables:

var current = new Date()
var expiration = new Date(current.getTime() + 24 * 60 * 60 * 1000)

Or you can combine it all in one line:

var expiration = new Date(new Date().getTime() + 24 * 60 * 60 * 1000)

Keep in mind that this will give you the date 24 hours from now. This may not be the same as "the same local time tomorrow" which can vary. Personally, I prefer the consistent approach of "a set time length" but your mileage may vary.

If you need the expiration to be a different number of days, simply adjust the constant 24 * 60 * 60 * 1000 (which represents the number of milliseconds in a day) by the desired number of days.
