Information About Administering the Device
System Time and Date Management
You can manage the system time and date on your device using automatic configuration methods (RTC and
NTP), or manual configuration methods.
Note
System Clock
The basis of the time service is the system clock. This clock runs from the moment the system starts up and
keeps track of the date and time.
The system clock can then be set from these sources:
• RTC
• NTP
• Manual configuration
The system clock can provide time to these services:
• User show commands
• Logging and debugging messages
