System Time and Date | 1077

•

Root Delay (sys.rootdelay, peer.rootdelay, pkt.rootdelay): This is a signed fixed-point number 
indicating the total roundtrip delay to the primary reference source at the root of the synchronization 
subnet, in seconds. Note that this variable can take on both positive and negative values, depending on 
clock precision and skew.

•

Root Dispersion (sys.rootdispersion, peer.rootdispersion, pkt.rootdispersion): This is a signed 
fixed-point number indicating the maximum error relative to the primary reference source at the root 
of the synchronization subnet, in seconds. Only positive values greater than zero are possible.

•

Reference Clock Identifier (sys.refid, peer.refid, pkt.refid): This is a 32-bit code identifying the 
particular reference clock. In the case of stratum 0 (unspecified) or stratum 1 (primary reference 
source), this is a four-octet, left-justified, zero-padded ASCII string, for example (see Appendix A for 
comprehensive list): the case of stratum 2 and greater (secondary reference) this is the four-octet 
Internet address of the peer selected for synchronization.

•

Reference Timestamp (sys.reftime, peer.reftime, pkt.reftime): This is the local time, in timestamp 
format, when the local clock was last updated. If the local clock has never been synchronized, the 
value is zero.

•

Originate Timestamp: The departure time on the server of its last NTP message. If the server 
becomes unreachable, the value is set to zero.

•

Receive Timestamp: The arrival time on the client of the last NTP message from the server. If the 
server becomes unreachable, the value is set to zero.

•

Transmit Timestamp: The departure time on the server of the current NTP message from the sender.

•

Filter dispersion is the error in calculating the minimum delay from a set of sample data from a peer.

The time and date can be set using the FTOS CLI.
