I almost mentioned that.  I periodically use reventlog to save the
eventlog to a file.  The xCAT timestamp correction works okay, except
sometimes the computed adjustment varies by a second or so.  This
makes doing diffs between reventlog output not work like I would like
(i.e. being able to see just any new entries).

This is one place I use impitool.  I have about 8 years of eventlog
information for all of our nodes, but I've never taken the time to
understand some of the needed sensor status/state or whatever
conversions needed to make the information meaningful.  I actually
just depend upon the xCAT reventlog interpreted information (another
plus for xCAT).
