Question

My WCF webservice is returning C# DateTime objects as JSON like this,

“/Date(1293793200000+1300)/”

I have found this,

Converting .NET DateTime to JSON

Which suggests this method for converting it using javascript,

var d = new Date();
d.setTime(1245398693390);
document.write(d);

The difference is that my date format has the +1300 in it, which seems to be my timezone, as I am +13 hours from GMT.

Can I somehow modify my service to adjust the value to an absolute number of milliseconds from epoch or can the javascript be modified?

Answer 1

You can ignore the time zone offset – the number of milliseconds is always relative to UTC (see the “DateTime wire format” section at http://msdn.microsoft.com/en-us/library/bb412170.aspx). The offset mostly indicates that the original DateTime value was of DateTimeKind.Local, but the serialized milliseconds since the epoch is always relative to GMT.
