Not a mystery at all.  The monitor archive records the ACU azimuth
which has a range of 90 to 630 degrees to account for the full one
and a half turn wrap.  By convention South is 360, so North is 180
or 540 depending upon wrap.

The data supplied by MIBs tags the data with UTC.  I suspect that
it is in the archive and can be displayed of you ask nicely.
It would be nice if that were the default.
