highUniqueId (4 bytes): A 32-bit, unsigned integer that contains the high-order bits of a unique 64-bit identifier for the bitmap data.
lowUniqueId (4 bytes): A 32-bit, unsigned integer that contains the low-order bits of a unique 64-bit identifier for the bitmap data.
tmMilliseconds (8 bytes): A 64-bit, unsigned integer that contains the milliseconds component of the timestamp that indicates when the bitmap data was generated. The timestamp (composed of the tmMilliseconds and tmSeconds fields), denotes the period of time that has elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds.
tmSeconds (8 bytes): A 64-bit, unsigned integer that contains the seconds component of the timestamp that indicates when the bitmap data was generated. The timestamp (composed of the tmMilliseconds and tmSeconds fields), denotes the period of time that has elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds.
