.SH NAME
-iseltime \- synchronize BMC SEL time with OS system time
+iseltime \- synchronize BIOS RTC and firmware SEL time from system time
.SH SYNOPSIS
-.B "seltime [-sx -NUPRETVF]"
+.B "iseltime [-sx -N node -U user -P/-R pswd -EFJTVYZ]"
.SH DESCRIPTION
-.I seltime
-is a program that uses IPMI commands to
-set the BMC SEL time from the OS system time.
-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 BMC time from the RTC during boot, but
-running this command may be necessary periodically if the system
-does not reboot for many weeks, for instance.
-Note that this command should not be run too frequently to avoid
-BMC timing issues. Once per day should be sufficient.
+.I 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.
-Run with no options, this command reads the BMC SEL time without
-setting anything.
-
-This utility can use either the /dev/ipmi0 openipmi driver,
-the /dev/imb Intel driver, the /dev/ipmikcs valinux driver,
-a driverless interface, or IPMI LAN.
+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.
.SH OPTIONS
-.IP "-s"
-Sets the SEL time (no more than once a day).
+Command line options are described below.
