Having a straightforward utility with which
to correct the clock on ones PC to an extremely accurate time source seems
to be the main reason for ClockAlign. As such, this program
should serve you well no matter what corner of the Internet you reside
To remove ClockAlign from your system, just delete the ClockAlign.exe from the directory you placed them in. Optionally, remove the ClockAlign registry key that's documented on the ClockAlign Home Page.
Nothing could be simpler! Just run the program by whatever method you prefer such as File Explorer, etc. If you've created a desktop shortcut to ClockAlign, ensure the Working Directory on the shortcut is the same as where all the ClockAlign files reside.
ClockAlign will then present you with a screen similar to this, except that the bottom status line will be blank. Click the button labeled 'Query Current Timebase' to query the current time from the default timebase which is a machine called tick.usno.navy.mil at the US Naval Observatory in Washington, DC, USA.
At this point, simply click the second button on the ClockAlign screen labeled 'Correct System Clock' to get a fresh sample and use it to reset your local system clock.
Make sure you reboot your machine after changing the TimeZone in Control Panel
ClockAlign uses TCP/IP port 37 (for RFC868 Time Protocol) or port 123 (for RFC2030 Simple Network Time Protocol - SNTP) so have your firewall manager map these ports to your preferred timebase if possible. ClockAlign has successfully operated with WinGate 2.0 in this mode, for example. I'm investigating SOCKS5 support, so drop a line if you need to have this capability.
If your network manager is operating a Time Protocol or NTP time server on a computer within your Intranet, then just define that computer's IP address or DNS name into ClockAlign via the Alternate Timebase menu option. Also, as most large Cisco routers are capable of supplying an NTP chime to their subnets, this may well be an option on your Intranet.
To have ClockAlign simply run, correct the clock and exit, just put some text on the command line. Anything at all will do. I have a shortcut in my Startup folder which has, on the Target field, the text: c:\Program Files\ClockAlign.exe /Run_Once
Recently, the U.S. Naval Observatory timebases (tick.usno.navy.mil and tock.usno.navy.mil) have stopped supporting the older Time/TCP and Time/UDP protocols. They now only support the much more accurate SNTP protocol. ClockAlign default to tick.usno.navy.mil when first installed, so be sure only SNTP protocol is selected when using tick and/or tock.
P.S. Check out http://www.eecis.udel.edu/~mills/ntp/servers.html for a current list of NTP Servers, worldwide. It will help keep your use of ClockAlign local to your geography, and therefore more reliable. Remember to use a Stratum 2 (Secondary) timebase whenever possible.
