How do I get javascript's Date.parse() in .Net?
===

I'm using .NET to generate a JSON file that has many `Date`s in it.

For compression, I want to store them as milliseconds since Jan 1, 1970 and not strings, then convert them to Javascript Dates.  But .Net's idea of milliseconds since 1970-01-01 don't match Javascript:

Javascript:

    Date.parse("2012-05-15T13:57:57.0000000+00:00")
    1337090277000

VB.Net:

    Date.Parse("2012-05-15T13:57:57.0000000+00:00").Subtract(New Date(1970,1,1)).TotalMilliseconds
    1337101077000.0

The difference is `10800` seconds.  The difference at 1970-01-01 is 0 and changes over time.

Is there a way to compute Javascript's idea of milliseconds-since-epoch from within .Net?
