Abstract:  These guidelines from the MFGM031M project provide an overview of
the components for quality clock synchronization. They complement
the SEMI E148 time synchronization standard by recommending
practices to implement SEMI requirements. When followed, these
guidelines will tag data with accurate timestamps that enable
data from multiple sources to be merged. This revision includes
additional guidelines for equipment internal time synchronization
and additional details about Network Time Protocol (NTP) commands
used to verify time synchronization quality and performance.
