+#       The most accurate keyword for the time/date is SHUTOUTC, but
+#       until 2009/9/30, there was a bug which set the month off by 1.
+#       The prior formats use MJD-OBS for time/date, and this is set
+#       in the db.  SHUTDAVR is supposed to be the key to the new
+#       shutter driver, but there were earlier periods where the value
+#       was 1.21, so we are keying on the MJD of the change.  Also
+#       note that historically (early 2008), SHUTOUTC was not
+#       available, forcing MJD-OBS in those periods.
