I am using Appcelerator Titanium, and I'm trying to parse a date string as a new Date object and then use the .getTime() function but it keeps returning "NaN"
var d = new Date("2014-02-01T00:00:00");
var time = d.getTime();
console.log(time); // returns NaN
Am I doing anything wrong here? It works when I create a new date for now, like this:
var d = new Date();
var time = d.getTime();
console.log(time); // returns correct value
I can't see why the first example is working but the second example is not.
You're trying to parse a UTC date time. In Titanium, when you try to parse the date, it will return invalid date. So you need to convert it to datetime string. You can use Convert UTC Date to datetime string Titanium to convert the time.

I'm working with Javascript within Google Sheets, and I'm having trouble converting or parsing a formatted timestamp, to ultimately extract the day as a numerical value.
My code:
var shopifyTimestamp = "2019-05-18 13:21:17 +0100";
var date = new Date(shopifyTimestamp);
Logger.log(date.getDay());
The output:
[19-06-10 17:40:56:107 BST] NaN
My goal is to extract the day number, for example, "18" from that timestamp.
However, it doesn't seem to convert it. I suspect my timestamp isn't in the correct format for the date() function, so it's about creating a function to parse it.
Hopefully, you can help me with that! :) Thank you so much.
The date object has a method like this for getting the day of the month as a number (1-31).
date.getDate();
18 is date.
var shopifyTimestamp ="2019-05-18 13:21:17 +0100";
var date = new Date(shopifyTimestamp);
console.log(date.getDate());
JavaScript's Date constructor supports ISO 8601 date strings. Without using any libraries, you can do something like this:
var shopifyTimestamp = "2019-05-18 13:21:17 +0100";
// will produce `2019-05-18T13:21:17+0100`
var isoDate = shopifyTimestamp.slice(0, 10)
+ 'T' + shopifyTimestamp.slice(11, 19)
+ shopifyTimestamp.slice(20);
var date = new Date(isoDate);
console.log(date.getDate()); // 18
Also note that you're looking for date.getDate(), rather than date.getDay(). The latter returns the numerical date of the week.
I want to convert systematic date into readable date format. However when I pass systematic date as argument to date constructor I get Invalid date response. How to do this properly in order to display formatted date such as dd-mm-yyyy for GMT+2 ?
var date = message.date; // => 1466663308000
var dateObject = new Date(date);
console.log(dateObject);
Console output:
Invalid Date
You have to make sure the timestamp value is a number and not a string:
var date = message.date;
var dateObject = new Date(+date); // note the +
console.log(dateObject);
Once you've got a valid date, there are many other questions here about formatting dates.
I tried the code, it is absolutely correct.
I can get the correct date
var d=new Date(1466663308000);
document.write(d);
But I tried another way:
var x = "1466663308000";
var d=new Date(x);
document.write(d);
I got the "Invalid date", so I guess, message.date should be a string, please try to long(message.date).
I have this application where I want to use you date, but the problem is that the date is not working as I expect.
I create a date object like this:
// Get today's date
today: function () {
// Create a new date
var date = new Date();
// Set to midnight
date.setHours(0, 0, 0, 0);
// Return our date
return date;
},
and If I output that date in my view I get yesterdays date at 23:00 hours....
Which looks like this:
2015-07-08T23:00:00.000Z
Does anyone know how I can get the date to be formatted properly?
Update
Just to elaborate a bit, I want to use the date to compare against records in the database. These records have the date applied to them, because the JavaScript is showing the local date time, it is not comparing correctly. Also there is a case where I am saving that date and I don't want it to save the local date.
based on your culture setting you can use the
date.toLocaleDateString()
this will give localized string format back
date.toUTCString();
date.toLocaleString();
date.toLocaleDateString();
date.toDateString();
date.toISOString();
Find your answer here :) And the best option is to use momentjs http://momentjs.com/
So, I ended up creating this function:
// Converts a date to a timeStamp
this.convertToTimeStamp = function (dateTime) {
// Get just the date
var date = dateTime.toDateString();
// Get the timestamp
var timeStamp = Date.parse(date);
// Return our timeStamp
return timeStamp;
};
If my understanding is correct, that should create the same date no matter what timezone / locale you are in.
on the aspx I am getting
date = /Date(1420460565000)/
I tried to parse it javascript date bject
var dateformatted = new Date(date);
However when I run it I am getting Invalid Data
How do I parse the c# DateTime object?
You could try this one:
var dateformatted = new Date(parseInt(date.substr(6)));
This works because substr function takes out the "/Date(" part, and the parseInt function gets the integer and ignores the ")/" at the end. The resulting number is passed into the Date constructor. Hence a new Date can be created.
I have a senario where i have to parse two dates for example start date and end date.
var startdate = '02/01/2011';
var enddate = '31/12/2011';
But if we alert start date
alert(Date.Parse(startdate)); i will get 1296498600000
but if i alert enddate
alert(Date.Parse(enddate)); i will get NaN
But this is working in other browsers except Chrome, But in other browsers
alert(Date.Parse(enddate)); i will get 1370889000000
Can anybody know a workaround for this?
If you want to parse a date without local differences, use the following, instead of Date.parse():
var enddate = '31/12/2011'; //DD/MM/YYYY
var split = enddate.split('/');
// Month is zero-indexed so subtract one from the month inside the constructor
var date = new Date(split[2], split[1] - 1, split[0]); //Y M D
var timestamp = date.getTime();
See also: Date
According to this
dateString
A string representing an RFC822 or ISO 8601 date.
I've tried your code and I also get NaN for the end date, but if i swap the date and month around, it works fine.
