Time Synchronization
The system clock runs from the moment the system starts up, and keeps track
of the date and time.
The date and time may be either set manually, or it may be received from an
SNTP server. If an external clock source, or an SNTP time server is not
defined, the manual clock setting is not persistent across boots.
This section describes how to set system time, and contains the following
topics:
• Global Settings (Clock Source)
• Manual Time Settings
• System Time from an SNTP Server
– SNTP Global Settings
– SNTP Authentication
–SNTP Servers
– SNTP Interface Settings
