NTP Relay

NTP Server of NCKU:

time.cc.ncku.edu.tw (140.116.241.73)
 

NTP Time Synchronization Service：

Why Accurate Time Synchronization Matters

  1. Security & Authentication: Accurate time is critical for validating digital certificates and authentication tokens.
  2. Logging & Analysis: Timestamps provide essential information for event sequencing and duration analysis.

Data Consistency & Replication: In distributed systems, synchronized clocks ensure proper data replication and consistency across nodes.

NTP Server

point 1. Campus NTP：time.cc.ncku.edu.tw ( 140.116.241.73 ) - (Stratum 2)

point 2. Domestic NTP：time.stdtime.gov.tw - (Stratum 1)

point 3. Global NTP：pool.ntp.org - (Stratum 2 / Stratum 3)

 

How to Configure NTP：

This service uses an in-house NTP server to provide stable time signals for IoT or dedicated devices within the campus that cannot access external networks, supporting research, data storage, and network operations.

 

Pre-check：

Ensure the device can ping time.cc.ncku.edu.tw (140.116.241.73) to confirm network connectivity.

 

Configuration Scenarios

Scenario 1: Device supports DNS

DNS settings: 163.28.112.1 / 163.28.113.1

NTP server: time.cc.ncku.edu.tw

 

Scenario 2: Device does NOT support DNS

Use NTP server IP directly: 140.116.241.73
