# TCP/IP Configuration Notebook Online Help

## General Tab

Use this tab to configure defaults for the following general parameters:

- RSH and LPR User Name

- Time Zone

The fields on this page are:

RSH/LPR User Name

  Specify the identifier to be used when a user on this computer attempts an RSH connection on a remote host. This user name is also used by your line printer (LPR) client. The user name can be up to 12 characters and is case-sensitive.

  The RSH/LPR user name is saved as the USER environment variable in the CONFIG.SYS file.

Time Zone

  Specify a single character string to represent all the following: the abbreviation for your time zone, the number of hours your time zone differs from Greenwich Mean Time (GMT), and the abbreviation for your daylight savings time. TCP/IP uses this time-zone character string to determine the correct date and time for clients located in different time zones.

  Select a time zone character string from the Time Zones list box or type your own string in the format SSSnDDD, as follows:

  SSS
    The label for your time zone. It must begin with a letter, have three characters, and can contain spaces. The default time zone is Eastern Standard Time (EST).
  n
    The number of hours your time zone differs from coordinated universal time (CUT), formerly Greenwich mean time (GMT). If you are east of GMT put a minus (-) sign before the number. If you are west of GMT, you can optionally put a plus (+) sign before the number. The n values range from -12 to + 12. The default number of hours is 5.
  DDD
    The label for your time zone when in daylight savings time. It must begin with a letter, have three characters, and can contain spaces. The default time zone is Eastern Daylight Time (EDT).

    If you do not observe daylight savings time, do not use a value for DDD.

  For example, Urbana, Illinois, is in the Central time zone, so you would use:

       CST6CDT

  Optional DST Parameters

  Optionally, you can specify the following Daylight Savings Time (DST) parameters:

  sm
    Starting month (1 through 12) of DST. The default is 4.
  sw
    Starting week (-4 through 4) of DST. The default is 1.
  sd
    Starting day of DST. If the starting week (sw) is not 0, then use values 0 through 6. If the starting week equals 0, then use values 1 through 31. The default is 0.
  st
    Starting time in seconds of DST. The default is 3600.
  em
    Ending month (1 through 12) of DST. The default is 10.
  ew
    Ending week (-4 through 4) of DST. The default is -1.
  ed
    Ending day of DST. If the ending week (ew) is not 0, then use values 0 through 6. If the ending week equals 0, then use values 1 through 31. The default is 0.
  et
    Ending time in seconds of DST. The default is 7200.
  shift
    The amount of time change in seconds. The default is 3600.

  If you want to use one or more of the optional DST parameters, you must give values for all of the parameters. If any value is not valid, the entire statement is considered not valid, and there will be no change to the time zone information.

  The optional DST parameters follow the DST zone identifier, and are separated by commas. For example:

      CST6CDT,3,0,15,3600,10,0,27,7200,3600

  For this example, DST starts on March 15 and ends on October 27. The starting time, ending time, and time shift are all default values.

Time Zones list box
  Select the abbreviation for your local time zone, if listed. Your selection will be inserted in the Time Zone field. If your time zone abbreviation is not listed in the box, you can create a new abbreviation using the format described in the help for the Time Zone field (above), and the type your abbreviation in that field.
