Tardis 2000/Tardis 2000 NT V1.3 Release Notes   
  
December 2000

What does it do?

Tardis 2000

Tardis 2000 is a Windows program that corrects your PCs clock. 
It is used where your PC is connected to a remote machine 
by TCP/IP, SLIP, or PPP.  A typical use would be to 
synchronise the clock on starting a SLIP/PPP connection to 
an Internet provider.  Another would be to have it running 
all the time in a LAN environment correcting the clock once an hour.

Tardis 2000 NT 

Tardis 2000 NT is a Windows NT service that corrects your PC's clock. 
It is used where your PC is connected to a LAN or the Internet
using TCP/IP, SLIP, or PPP.  A typical use would be to 
it running in a LAN environment correcting the clock once an hour. 
To verify that the installation has succeeded, start the Windows NT
Control Panel and double-click on the Services icon.  The resulting
dialog should list Tardis as one of the installed services.  
Note:For correct operation on NT4.0 during the switchover from daylight savings time
service pack 6 or greater should be installed.


Thats about it really.  

I hope it does something simple simply.
