9.1 OVERVIEW

9

Time stamp values are snapshots of the local 256 bit sample counter taken at the time of the transmission or receipt of the
first message in a time stamp sequence. This could be done either in software or hardware, provided the jitter is limited to
less than plus or minus 130



s. A fixed bias in the time stamp is acceptable, provided it is the same for all terminals.
