Log into the device with Telnet or SSH. Enter privileged mode by typing enable and entering your enable password.
Enable DNS lookup
Make sure DNS lookups are enabled on your device so it can be synced to an NTP server. Run the following command. Replace 8.8.8.8 8.8.4.4 with the DNS servers you’d like to use.
enable ip domain lookup ip name-server 8.8.8.8 8.8.4.4 exit
Set the clock, time zone, and NTP server
There are four locations shown as examples. To see the available global zones from NTP Pool, refer to https://www.ntppool.org/zone/@.
For each example, replace set date MMDDHHmmYYYY with the current time and date at the time the setting was applied. If you use a zone not shown below, also update set system time-zone EST and ntp server north-america.pool.ntp.org, for example.
- North America, Eastern Time (UTC-5)
- Europe, Central European Time (UTC+1)
- Brazil, Brasília (UTC-3)
- Australia, Sydney (UTC+11)
North America (specifically Eastern Time, UTC-5):
configure set date 010109002018 set system time-zone EST delete system ntp set system ntp server ntp server north-america.pool.ntp.org commit save
Europe (specifically Central European Time, UTC+1):
configure set date 010109002018 set system time-zone CET delete system ntp set system ntp server ntp server europe.pool.ntp.org >commit save
Brazil (specifically Brasília, UTC-3):
configure set date 010109002018 set system time-zone BRT delete system ntp set system ntp server ntp server br.pool.ntp.org commit save
Australia (specifically Sydney, UTC+11):
configure set date 010109002018 set system time-zone AEST delete system ntp set system ntp server ntp server au.pool.ntp.org commit save
