nwfstime

NWFSTIME(1)							     nwfstime							       NWFSTIME(1)

NAME

       nwfstime - Display / Set a NetWare server's date and time

SYNOPSIS

       nwfstime [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] [ -s ]

DESCRIPTION

       nwfstime displays a NetWare server's date and time. You can also set a NetWare server's date and time from the local time.

OPTIONS

       -h
	  With -h nwfstime prints a little help text.

       -S server
	  is the name of the server you want to use.

       -U user
	  user is the user name to use for login. To set the server's time, you need supervisor privileges.

       -P password
	  password  is	the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwfstime
	  prompts for a password.

       -n
	  -n should be given if no password is required for the login. As you need supervisor privileges for  setting  the  date  and  time,  this
	  option is probably not used very often.

       -C
	  By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
	  this conversion by -C.

       -s
	  With -s, nwfstime sets the file server's date and time according to the local date and time.
