Chrome与Firefox中的Javascript日期不正确

Question

I'm getting incorrect dates in Chrome...

My code looks like this..

Title contains "2013-06-14T00:00:00", it was a DateTime in C# returned from WebAPI

As you can see here on both browsers..

When I add it to a new javascript date like this.. var dt = new Date(title)

I get different dates in different browsers...

Answer 1

Looks like Firefox is assuming this datetime format without timezone is local time and Chrome/Webkit is assuming it's UTC.

If the datetime returned from the api is UTC, simply append a "Z" to the end of the string, so it becomes "2013-06-14T00:00:00Z", which indicates the time is in UTC, then you will get the same result in the two browsers.

Answer 2

Convert timestamp to ISO 8601 formatted string in C#, for eg

var title = "14 JUN 2013 00:00:00" // printed from C#

Then use Date constructor

var date = new Date(title);

If you don't specify timezone the local timezone in the client machine will be set to the given time. If you specify the timezone, needed calculations will be done to convert the date to local timezone.

var title = "14 JUN 2013 00:00:00";
var date = new Date(title); // Fri Jun 14 2013 00:00:00 GMT+0530 (IST)

var title = "14 JUN 2013 00:00:00 GMT";
var date = new Date(title); // Fri Jun 14 2013 05:30:00 GMT+0530 (IST)

var title = "14 JUN 2013 00:00:00 GMT-0400";
var date = new Date(title); // Fri Jun 14 2013 09:30:00 GMT+0530 (IST)
