Abstract
Methods, apparatus and data structures are described for representing, storing and manipulating date/time information in an 8-byte timestamp format. By limiting date/time information to a predetermined range and specifying a single date/time structure, an 8-byte timestamp is generated that is capable of conveying the same operational information as conventional 24-byte timestamps, yet which can be more efficiently generated, more efficiently stored, and more efficiently evaluated in boolean operations.
