Setting the System Time
Synchronized clock times are critical for a variety of purposes, including distributed applications
that require time synchronization, analyzing event logs from different devices, ensuring cron
jobs execute at the correct time, and ensuring that applications that use system time to validate
certificates find the correct time. For example, in the case of audit logs, the time stamps on
different network devices should be accurate to within about a second of each other to correlate
events across multiple devices.
You can view the current system time at the top of any Network Voyager page.
You can set the system time using any of the following methods:
Set the date and time manually.
Access a time server once.
Configure Network Time Protocol to access time servers for continuing clock
synchronization. For more information, see “Network Time Protocol (NTP)” on page 475.
Set the system time either manually or by using a time server when you initially configure the
system. You might need to set it again when you bring the system up after it has been down for a
period of time. Use this procedure also to specify the local time zone.
Note
When you reset the system time, the routing table is reset and existing connections might be
terminated.
If you have not enabled NTP, you can set the system time once from a time server. For
information on configuring NTP to update the time on a regular basis, see “Network Time
Protocol (NTP)” on page 475.
