System clock

On a RUCKUS device, you can manually set the system clock with the time and date you specify. The system clock settings are retained across power cycles.

The operation of the device does not depend on the date and time. A RUCKUS device will function properly despite incorrect date and time value. However, since logging, error detection, and troubleshooting use the date and time, you should set the clock correctly. Time values are limited to between January 1, 1970 and December 31, 2035.

If NTP servers are configured, the NTP server automatically updates and overrides the system clock.

In this section:

  1. Daylight saving time
    Some countries around the world have adopted adding an extra hour of daylight to the evenings during the summer time to make use of extra light. The extra hour is removed at the start of the winter. Daylight saving is more effective in countries further away from equator.
  2. Time zones
    Time zone settings affect the local time and potential summer time changes for a specific region. Time zones are measured by the time ahead or behind Greenwich Mean Time (GMT) and expressed as Universal Time Coordinated (UTC) with a positive or negative sign and a number representing hours.
  3. Setting the clock parameters for the device
    The date and time values set on a device are used for logging, error detection, and troubleshooting. ICX devices have the capability to retain date and time programmed in Real Time Clock (RTC) register even when power is removed from the device.
    Please confirm if the below statement is accurate for ICX 7150-ES devices?
    However, ICX 7150 and ICX 7650 do not have this capability because they were designed without an RTC battery, therefore they do not retain clock date and time in case of power outage. To avoid loss of accurate date and time, configure the NTP server to manage the clock because time synchronization from NTP server overrides the switch clock.
