  81 +There are errors in some of the Cassini MAG data in this data set
  82 +due to incorrect handling of leapseconds. The errors are as follows:
  83 +* 2012-07-01 00:00:00.000 - 2015-07-01 00:00:00.000 - Error : +1 s
  84 +* 2015-07-01 00:00:00.000 - 2017-01-01 00:00:00.000 - Error : +2 s
  85 +* 2017-01-01 00:00:00.000 - End of Mission - Error : +13 s
  86 +
  87 +The time tags can be corrected by subtracting the error from current time
  88 +values. This error was created during the conversion of the data from binary
  89 +to ASCII performed at the PDS/PPI node. It does not exist in the original
  90 +binary data files available from the Cassini MAG team. The PPI node will
  91 +correct this error in it's data holdings at a future date.

  94 +Some versions of these data were determined to contain timing errors,
  95 +including both backwards and repeated times. These timing errors have not
  96 +been corrected in the data files.
