This appears to be a JavaScript date value, which is provided in terms of milliseconds elapsed since the epoch of January 1st, 1970.

You can convert it to a DateTime several ways in C#.

For example (from the link above), you can add the ticks elapsed since the JavaScript epoch. To convert from milliseconds to ticks, multiply by 10,000. Therefore you could write the following:

new DateTime(1970, 1, 1).AddTicks(1252368000000 * 10000);
