Summary: Page: 153
Change: In NTP, TIME_ZERO represents a point in time in 1900.  If this was followed by RTPS with its 31-bit field for positive seconds, the maximum point in time would be in 1968, long before RTPS was invented.  Therefore the meaning of TIME_ZERO must be specified here.  Additionally, leaving only 31 bits for positive seconds and assuming 1970 is used as TIME_ZERO, RTPS times are only valid through 2038.  Is there a need for a sign bit in “seconds”?
