a client/server self test. This checks to see if the basic time server
functionality for the program is working by making a client time request from
the same computer. It is accessed from the Client options
tab in ClockWatch.
time serving functionality of ClockWatch running on computer.
a time request coming from another computer on a network
in pinpointing network communication and access problems with clients
communicating with server.
Server test screen)
Current port and protocol settings in ClockWatch
for serving time to clients currently being tested.
Localhost refers to the
current machine and resolves to 127.0.0.1. This is also called a loopback test.
Time-sync protocol used to
communicate with clients.
Number of TCP or UDP
port used to communicate with clients.
Shows the status of the ClockWatch and Windows Time service. ClockWatch service
is a background process that runs whenever Windows is running. It can be on or
off for the test.
Windows time is the native time client in Windows.
Note: If using SNTP protocol to serve time in ClockWatch, the Windows
Time service should NOT be running.
Communicates with timeserver by
sending a time request in the given protocol.
Check that localhost can be resolved to an IP address
Common connection test to verify
ability of this computer to respond to pings. The ping utility uses the ICMP echo request and echo reply packets.
Time-sync protocol used to communicate with the
timeserver using the NIST protocol.
Common time-synchronization protocol.
Simple Network Time Protocol
Time protocol, TCP connection time.
Time protocol, UDP connection type. Also called net date.
Protocol used in the test to run.
This should be same as the server.
Whether the test uses a TCP or UDP type connection.
Port number used to communicate with timeserver in test.
This should be the same port as the server.
Toggle all tests on or off.
Interval in seconds to wait for the timeserver to respond for each test. If the server does not respond within the interval, then the test fails.
Test Results Section
Shows the results of the communications tests.
Pass (Gd) Test Checkmark
The timeserver has responded to the test with the appropriate response.
Fail (Bd) Test Checkmark
The timeserver has failed to respond to the test on the port specified, or the response was in an unexpected format.
The string returned by the timeserver or the results of the test.
