Set Date and Time from NTP Servers

If the NTP server is unable to synchronize the current date and time on the router, a system log message similar to the following appears:

"time error %.0f over %d seconds; set clock manually". 

To set the date and time from all NTP servers configured at the [edit system ntp server] hierarchy level to determine the correct time, use the set date ntp command:

user@host> set date ntp 

 
You do not need to reboot the router when you use the set date ntp command.



 

To set the date and time from a NTP server configured at the [edit system ntp server] hierarchy level to determine the correct time, use the set date ntp command:

user@host> set date ntp <ntp-server>

To set the date and time from multiple NTP servers configured at the [edit system ntp server] hierarchy level to determine the correct time, use the set date ntp command:

user@host> set date ntp <ntp-server>

ntp-server—IP address of one or more NTP servers to query. When querying more than one server, enclose the IP addresses in quotes using the format "ip-address ip-address". For example:

user@host> set date ntp "200.49.40.1 129.127.28.4"

10 Feb 13:50:21 ntpdate[794]: step time server 129.127.28.4 offset 0.000163 sec
