None of the formats you mentioned include milliseconds.  The only way I have
been able to do it is to manually produce a date string using "yyyy/MM/dd
HH:mm:ss.fff".  However, the JScript Date() object constructor that accepts
strings only seems to be able to read strings that do not contain
milliseconds.  So... I end up having to manually parse this string in
JScript to extract the individual components and then build a JScript Date()
object by passing in month, day, year, etc.. to the alternate Date()
constructor.  I wish there was a more straight-forward way of doing this.  I
made a JScript function that does it:

function ExtractDate(Text)
{
  return new Date(parseInt(Text.substr(0,4),10),
                  parseInt(Text.substr(5,2),10)-1,
                  parseInt(Text.substr(8,2),10),
                  parseInt(Text.substr(11,2),10),
                  parseInt(Text.substr(14,2),10),
                  parseInt(Text.substr(17,2),10),
                  parseInt(Text.substr(20,3),10));
}

This is sort of clunky, but it works.  I just wish there was a more elegant
translation between the two types.
