CubeIP - Time and Date synchronisation with Windows XP.

Later versions of XP may automatically configure the SNTP server so it is always worthwhile data logging with the CubeIP before changing any settings on the PC.

In order to confirm that the sntp service is running on the PC to be used as the time server.
From the DOS command prompt enter:

  w32tm /register
  net start w32time

The first command adds the required entries in the Registry.
The second command starts the timeserver service.

The precise date and time the CubeIP uses for the data log timestamps is acquired from a SNTP servers. The CubeIP uses the the NTP pool which is a dynamic collection of networked computers that volunteer to provide highly accurate time via the Network Time Protocol to clients worldwide. The machines that are "in the pool" are part of the pool.ntp.org domain. More than 1300 time servers provide time to some six million systems around the world.

A Windows XP PC can be used as an SNTP server to provide time to the CubeIP. The PC can have its internal hardware clock automatically synchronised to an international standard by setting it to be 'Automatically synchronised with an Internet time server.'

The following links to Microsoft Help and Support pages provide comprehensive information on setting and testing the SNTP service.

How to configure an authoritative time server in Windows XP

To determine the current configuration of the client, use the following command from a command prompt:

C:\>net time /querysntp
The current SNTP value is: pool.ntp.org,0x1
The command completed successfully.

or if not configured:
This computer is not currently configured to use a 
specific SNTP server.

Note:
SNTP uses User Datagram Protocol (UDP) port 123. If this port is not open to the Internet, you cannot synchronize your server to Internet SNTP servers.
