What could be the reason behind the varying outcomes browsers provide for the JavaScript expression new Date(-105998400000)?

When I use ASP.NET MVC 3 with the default Json serializer, I notice that dates from my JsonResults come back in the format /Date(-105998400000)/. To handle this, I extract the number and create a new Date object with this value. However, I am experiencing inconsistency between IE and Chrome.

var date = new Date(-105998400000);

You can check out my jsfiddle to see how different browsers display the results:

IE10 - Mon Aug 22 23:00:00 EST 1966
Firefox - Tue Aug 23 1966 00:00:00 GMT-0400 (US Eastern Standard Time)
Chrome - Tue Aug 23 1966 00:00:00 GMT-0400 (US Eastern Daylight Time)

Interestingly, two of my clients are seeing the August 22 date in Chrome.

I am puzzled by the fact that the same UTC milliseconds value returns different results in different browsers when creating a new Date object. Can you explain why this happens?

Answer №1

In my original solution to this problem, I opted to utilize ISO 8601 dates from the Json.NET serializer rather than UTC millisecond offsets from the outdated ASP.NET MVC3 Json serializer. You can find more details about my approach here.

I gained valuable insights into this issue thanks to user dandavis.
