To add a time service to the Time Service list

  1. Locate and open the timesrvr.txt file.

    The timesrvr.txt file contains time service information.

  2. In the timesrvr.txt file, add the time service you want to use. Use the following format:

    Description (servicemen)

    For example:

    National Institute of Standards and Technology (time.nist.gov)

  3. Save the file.
NoteTo use a file different from the timesrvr.txt file for time service options, change the setting of the ADSKSIGTIMESRVR environment variable. For example, change the variable to c:\temp\mytimelist.txt.
