NAME

       iseltime - synchronize BIOS RTC and firmware SEL time from system time

SYNOPSIS

       iseltime [-sx -N node -U user -P/-R pswd -EFJTVYZ]

DESCRIPTION

       iseltime  is  a program that allows synchronizing the hardware time values for RTC (BIOS Real-Time-Clock)
       and SEL (IPMI firmware SEL time) with the OS system time.  Run without options, iseltime  shows  each  of
       these times to show whether they are the same or not.

       The  OS system time should be in sync with the BIOS Real-Time-Clock.  The OS system time may also be kept
       from drifting via an NTP server.  Normally the BIOS will set the firmware SEL time from  the  RTC  during
       boot,  but  running  this  command may be necessary periodically if the system does not reboot for a long
       time, for instance.  Note that some applications may not handle setting the  time  backward  well.   Note
       that  this command should not be run too frequently to avoid firmware timing issues. It should not be set
       more than once per day.

OPTIONS

       Command line options are described below.

       -s     Set  the  RTC  and  IPMI firmware SEL time to match the system time.  This should not be performed
              more often than once a day.

       -x     Causes eXtra debug messages to be displayed.

       -N nodename
              Nodename or IP address of the remote  target  system.   If  a  nodename  is  specified,  IPMI  LAN
              interface is used.  Otherwise the local system management interface is used.

       -U rmt_user
              Remote username for the nodename given.  The default is a null username.

       -P/-R rmt_pswd
              Remote password for the nodename given.  The default is a null password.

       -E     Use the remote password from Environment variable IPMI_PASSWORD.

       -F drv_t
              Force  the driver type to one of the followng: imb, va, open, gnu, landesk, lan, lan2, lan2i, kcs,
              smb.  Note that lan2i means lan2 with intelplus.  The default is to detect  any  available  driver
              type and use it.

       -J     Use   the  specified  LanPlus  cipher  suite  (0  thru  17):  0=none/none/none,  1=sha1/none/none,
              2=sha1/sha1/none, 3=sha1/sha1/cbc128, 4=sha1/sha1/xrc4_128, 5=sha1/sha1/xrc4_40,  6=md5/none/none,
              ... 14=md5/md5/xrc4_40.  Default is 3.

       -T     Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2, 2=MD5, 4=Straight Password, 5=OEM.

       -V     Use  a  specified  IPMI  LAN  privilege  level.  1=Callback level, 2=User level, 3=Operator level,
              4=Administrator level (default), 5=OEM level.

       -Y     Yes, do prompt the user for the IPMI LAN remote password.  Alternatives for the password are -E or
              -P.

       -Z     Set the slave address for a local MC
