ClockWatch Main Page
How do the CW Clients communicate with the Server?
Independently, a workstation running ClockWatch Client requests time from
Server over the LAN or WAN using the sockets protocol. Server responds to each client with correct time, logging client request.
Client adjusts time for time zone and sets internal clock to correct time.
How many Clients can the Server handle?
Since ClockWatch uses a lightweight networking approach, CW Server can
handle up to 2000 clients.
Do I need a license for each CW Client?
Yes, each workstation running ClockWatch client needs to be licensed. ClockWatch
Enterprise offers a cost-effective option for larger networks (greater
than 15 clients).
I have to use ClockWatch Client to talk with CW Server?
No, ClockWatch server maintains the O/S time on the server it is running. Other
means can be used to time-synchronize a network. ClockWatch Client offers many advantages
including time display options, setting options, graphs, ease of installation and logging.
Network / LAN Issues
network traffic is added with each CW Client?
ClockWatch requires minimal network resources. Time settings are made (at most)
several times each day. Each time setting packet is just 537 bytes.
Will it work with my mainframe or mini computer?
ClockWatch Client/Server will run on a network maintained at standard time
through other means on the network which it is running. Currently ClockWatch runs only on
Windows 32 bit platforms.
Will it work on my token ring LAN?
If your token ring supports Sockets (most do), ClockWatch can be used.
CW Service run even when there is no one logged in?
Yes, if ClockWatch Service is set to start automatically, ClockWatch will
start when Windows is started, even if there are no users currently logged on.
I'm using CW Client and
I don't want to give users access to ClockWatch's controls. Can this be done?
ClockWatch Client can be installed and run as a Service, restricting
access to those authorized. ClockWatch
Enterprise offers centralized control by the server administrator.
Can ClockWatch be installed as an application for a regular user
permissions must be set in Windows NT/2000 to change the time?
Making ClockWatch accessible by regular users under Windows NT/2000 is a
- A regular version of ClockWatch Pro, Client or
Server must first be installed by someone with full administration privileges.
- A special user shell version is available from Beagle Software.
This version allows the user to install the application for their login and gives the user
access to the ClockWatch application.
- The group that the user belongs to must have the right to
"Change the system time" in the Windows NT policy administration.
In Windows 2000 this option can be found under Security
Settings->Local Policies->User Rights Assignments
On Windows XP machines:
group that the user belongs to must have the right to "Change the system
time" in the Local Security Settings administration. In Windows XP this
option can be found under Administrative Tools->Local Security Policy
ClockWatch as an NT Service (CW Server, CW Client)
An NT service is a specific system function that runs in a
special area under Windows NT. ClockWatch Server contains a module, which can be installed
as a Service under Windows NT. This allows ClockWatch to run in the special service area
of the operating system. In ClockWatch server, the program maintains a copy of the
run-time options for use by the service module. When running as a service, ClockWatch does
all the clock synchronization activities without intervention running from the parameters
specified by the user using the normal ClockWatch application.
To install ClockWatch as a service:
Install and configure ClockWatch Server on the system.
The service uses the ClockWatch parameters you specify in the regular ClockWatch
Register the Service module by choosing "Register CW Service" under the file
menu. This will register the service with the operating system.
Start and run the service like any other service by using the Windows NT administrative
interface. In Windows 2000, this can be found under Administrative
To start the ClockWatch service, use the Control Panel Services applet. This applet lets
you start, stop, pause or continue the execution of services. You can also use it to
specify if you want ClockWatch to be started at boot time, and if you want a simple user
interface to be visible.
ClockWatch Service must be run in the System context.
Is there a way to automate the
installation of CW Client to workstations?
Yes. ClockWatch Client features a simple, yet powerful, option that lets you include a custom installation template.
This makes installing ClockWatch Client with company-specific values simple and direct. This
also allows for company-wide deployment of customized ClockWatch Client installations without
modifying the original installation package. The installation files can be shared or
copied to a network share for installation.

ClockWatch work behind
The current version of ClockWatch can be configured to work
behind corporate firewalls or Proxy servers. See ClockWatch behind firewalls for detailed information.
ClockWatch work with
my dial-up Internet connection?
ClockWatch will work with all dial-up Internet Service
providers that allow access to the Internet.
write to the NT Event log?
No, ClockWatch maintains its own logs. This allows the logs to
be written across a network or gathered for archives or analysis.
Does it work with external master clocks or time signals?
Yes, ClockWatch can run on a Windows 95/98/NT/2000 computer that is
maintained by master clocks, radio clocks or other external time sources.
Will it control external mechanical time clocks?
Converters are available to connect time clocks to a Windows computer
through the serial port. Beagle Software offers a time stamper, DocuClock,
that stamps receipts with the exact time.
