OS10 Enterprise Edition User Guide Release


System clock

OS10 uses NTP to synchronize the system clock with a time-serving host. If you do not use NTP, set the system time and the timezone. The hardware-based real-clock time (RTC) is reset to the new system time.

You can set the current time and date after you disable NTP. When NTP is enabled, it overwrites the system time.

  • Enter the time and date in EXEC mode.
    clock set 
                                        time year-month-day

    Enter time in the format hour: minute: second , where hour is 1 to 24; minute is 1 to 60; second is 1 to 60 (enter 5:15 PM as 17:15:00).

    Enter year-month-day in the format YYYY-MM-DD, where YYYY is a four-digit year, such as 2016; MM is a month from 1 to 12; DD is a day from 1 to 31.

  • Enter the timezone in CONFIGURATION mode.
