A jscript Date is an automation object (VARIANT with VT = VT_DISPATCH for ATL). The easiest way to get its value passed would be calling its toUTCString method and pass the string in UTC time instead. If you want to pass the object directly to save some scripting, call the getUTCFullYear/getUTCMonth/getUTCDay/getUTCHours/getUTCMinutes/getUTCSeconds/getUTCMilliseconds/getTimezoneOffset methods via its IDispatch interface to get the exact time.

You can view the object's type library in jscript.dll using OleView.
