This tip was respectfully gleaned from TID 10011518.
Network Time Protocol (NTP) provides a means for networked computers to serve and maintain accurate time on the Internet. Using NTP to poll time from External Time source over TCP/IP is easy with NetWare 5.
- If the server is a NetWare 5.0 server, then install Support Pack 5 or later. If the server is a NetWare 5.1 server, then install Support Pack 1 or later.
- On the SINGLE or REFERENCE time server, load MONITOR.NLM | Server Parameters | Time, and change the following parameters
TIMESYNC Configured Sources = ON
TIMESYNC Time Sources = IP_address_of_Internet_time_source:123; Where 123 is the NTP port on that time source.
- Verify the Timesync configuration information has been updated / changed in the SYS:SYSTEM\TIMESYNC.CFG and SYS:SYSTEM\AUTOEXEC.NCF files.
- At the console prompt, Unload TIMESYNC, Load TIMESYNC
Example: TIMESYNC Time Sources = 126.96.36.199:123;
Possible Internet Time sources:
- U.S. Naval Observatory - 188.8.131.52:123;
- Lawrence Livermore National Laboratory - 184.108.40.206:123;
- NASA Ames Research Center - ntp.nasa.com:123;
- MIT - 220.127.116.11:123;
- NIST Central Computer Facility - 18.104.22.168:123;
