Server Options Tab The server tab offers a choice for the location, type and type of connection to the timeserver you will be using. You can choose a NIST timeserver or a Daytime format server. You can also connect directly to the server over the Internet of through a proxy server. If an Internet connection is unavailable then you can call the timeserver on the phone using the computer's modem.
NIST Timeserver Frame Use Internet When checked communicates directly to one of NIST timeservers over an existing Internet connection, expecting the NIST formatted time string in reply. TCP/IP Port 13 is used for this connection. Dial ISP When checked will first dial your ISP to make a connection to the Internet and then sync the clock using the NIST timeserver specified. For configuration options see the Auto-dial ISP section. Direct modem connection When checked uses the modem to call the NIST directly and sync up time signals over the phone line. Does not use the other options in this frame. For configuration options for direct connection see the section on Direct Modem Connection. <List of Server Locations> The radio buttons show the URL of the NIST timeserver locations around the US. Find Next Available server When enabled, this option will find next available server if the current server is unavailable,. This will try the next server on the list on the next setting attempt. It will work through the list of NIST servers list till one is found. The server will default to the server originally selected when restarting the application.
Other Timeserver Frame Use other server (CW Pro, Server) When checked, communicates directly to the timeserver at the address specified over the Internet expecting the formatted time string specified in reply. TCP/IP Port 13 is always used for this connection. ClockWatch Server (CW Client) When checked, communicates directly to the ClockWatch Server at the address specified over the LAN or WAN expecting the NIST formatted time string in reply.
Address of timeserver Enter the IP address of name of the timeserver (i.e.: time-a.nist.gov or 167.166.116.1). ClockWatch Client users should enter the IP of the ClockWatch Server. Hint: Check the Beagle Software web site (http://www.beaglesoft.com) for a current list of public Daytime time servers.
Difference in hours Specifies the difference in hours between the timeserver and your computer. ClockWatch will correct the time received from the timeserver this amount before comparing the computer's clock to standard time. This is the time in hours that the timeserver is ahead or behind your computer.
For example, If in the same time zone, enter '0' for no difference, if the timeserver is an hour ahead, enter '1', if an hour behind, enter '-1'.
Note: the value in the Difference in hours field is used in time comparisons any time the Daytime format is selected.
Format Specifies what kind of format the response from the timeserver will be in. For a description of the actual format see NIST and Daytime time.Daytime Protocol - used by a wide variety of timeservers throughout the world. It is expected that the string returned be in the local time and in English. NIST Specific format used by the National Institute of Standards and Technology. This string is always in standard UTC time. ClockWatch Server also uses this format to communicate with ClockWatch Client. Tip: If the format of a timeserver is unknown, try the more widely deployed
Daytime format before trying the NIST format.
Proxy Timeserver Frame The proxy server option allows use of ClockWatch behind a proxy server. This option is not available with ClockWatch Client. Use proxy server When checked, communicates to the timeserver through the proxy server specified expecting the formatted time string specified in reply. The proxy server serves as an intermediary, passing the request on to the timeserver and then relaying the response back to ClockWatch. For more information about using ClockWatch with proxy servers see the user guide section on firewalls.
Address of proxy server: Enter the IP address of name of the local proxy server (i.e.:
myfirewall or 90.1.11.1) that is set up to handle the time requests.
Port: Enter the specific TCP/UDP port number used for making the socket connection. Specify the port used on the proxy server for time requests. The network administrator must configure this port for time requests. This port will take the request from ClockWatch and relay it to the address and port mapped for time requests.
