System Time Elements

The system clock maintains time according to Coordinated Universal Time (UTC). Configure information time zone and summer time (daylight savings time) parameters to correctly display time according to the local time zone.

Time elements include:

• Zone

• Summer Time Conditions

• NTP

• SNTP

• PTP

• Time-of-Day Measurement (ToD-1pps)

• GNSS

• CRON

Use the following CLI syntax to configure system time elements. The authentication-key des keyword is not supported if the 7705 SAR node is running in FIPS-140-2 mode.
