3.6.3 SNTP/UTC Time Clock

The Simple Network Time Protocol (SNTP)/UTC feature provides LMS4000 devices with an

accurate clock for time stamping events in the log file.

SNTP/UTC Time Clock operation is illustrated in Figure 28.

Figure 28 SNTP/GMT Time Clock

The CCU, acting as an SNTP time client, regularly resynchronizes to one of several NTP

Servers from which it obtains UTC (Universal Coordinated Time). The CCU resynchronization

and retry periods can be set by the operator. The resynchronization period is the time between

a successful CCU resynchronization and the next CCU resynchronization attempt, typically

set to one hour. The retry period is the time between an unsuccessful resynchronization

attempt and the next resynchronization attempt, typically set to 30 seconds.

The operator can configure the CCU to act as an SNTP time server to the EUMs and

broadcast time information to all EUMs after it has synchronized with the NTP server. It also

broadcasts this information whenever an EUM powers up and registers.

UTC, the international time standard, is based on a 24-hour clock. It is the current term for

what was commonly referred to as Greenwich Mean Time (GMT). Universal time is based on

a 24 hour clock. SNTP, specified in RFC1769 and RFC2030, is a simplified version of NTP,

which is specified in RFC1305.

By default, the CCU SNTP client is disabled.OnceSNTPisenabled, the CCU tries to

synchronize with an NTP server. The operator can configure the CCU to synchronize with

• a local router or network device, if the router or network device is configured as an

NTP time server,

• any open-access NTP server of the operator’s choosing, or

• one of the five factory-default open-access NTP servers listed below:

• 132.246.168.148 time.nrc.ca stratum 2, Canada

• 140.162.8.3 ntp.cmr.gov stratum 2, US

• 136.159.2.1 ntp.cpsc.ucalgary.ca stratum 2, Canada

• 192.5.5.250 clock.isc.org stratum 1, US

• 127.0.0.1 local host (the CCU itself)
