Can I configure multiple NTP servers ?
There are two scenarios:
Scenario 1: Devices that cannot access external networks
(Recommended: configure only one server)
NTP server: time.cc.ncku.edu.tw or 140.116.241.73
Scenario 2: Devices that can access external networks
(Recommended: configure two servers)
First: time.stdtime.gov.tw
Second: pool.ntp.org
