A single 64 bit value is used to represent the time. This value represents the number of seconds since 0h (UTC) Jan. 1, 1900. There is an implied binary point betweeen the upper 32 bits and lower 32 bits (this is referred to as a 32.32 fractional representation). For example a binary value of 00000000 00000000 00000000 00000011 10000000 00000000 00000000 00000000 represents 3.5 seconds since Jan 1, 1900. 59<p> 60<hr><h2>Constructor & Destructor
