'installpatch' and 'backoutpatch' scripts provided with each patch.
 
For Solaris 7-9 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be
described below as special instructions.  The following example
installs a patch to a standalone machine:
 
       example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
       example# patchrm 104945-02

This patch adds a new configuration option to the /etc/inet/ntp.conf
file.  The option is:
 
        slewalways yes | no
 
If you turn this option on xntpd will try to always slew the time and
will never make large steps backwards or forwards.
 
It is advised that if you do turn on slewalways you also select:
 
        disable pll
 
Without this option xntpd will not be able to correct time differences
greater than 128ms.
