Not familiar with VB.net, but in Java it is defined as:

the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC.

I did a quick search for "utc 1970 vb.net" and found a number of hits. It sounds like .ticks in .NET is defined as:

In .NET, DateTime.Ticks is the 100-nanosecond intervals that have
elapsed since 12:00 A.M., January 1, 0001

So one suggestion was to construct a date object for January 1, 1970, then subtract it from now. This is a C# snippet:

Al Pascual : Code Snip Collection "c# datetime utc date to javascript millisecond representation "

public double MilliTimeStamp(DateTime TheDate)
        {
            DateTime d1 = new DateTime(1970, 1, 1);
            DateTime d2 = TheDate.ToUniversalTime();
            TimeSpan ts = new TimeSpan(d2.Ticks - d1.Ticks);

            return ts.TotalMilliseconds;
        }
