5.4.1.3 DESDKD Usage Considerations

1.  Care must be exercised in using the special date and time
    data elements contained in each CA MICS file. As the
    file's granularity increases in higher timespans, certain
    fields lose significance and should not be referenced:

    o HOUR should not be used in MONTHS and YEARS.
    o DAY and DAYNAME should not be used in WEEKS, MONTHS, or
      YEARS.
    o WEEK should not be used in MONTHS or YEARS.
    o MONTH should not be used in YEARS.

2.  The data elements STARTTS and ENDTS have different
    meanings when used in the DETAIL timespan from when they
    are used in the DAYS, WEEKS, MONTHS, and YEARS timespans.
    The ENDTS and STARTTS, when appearing in the higher
    timespans, indicate the span of time over which the data
    has been summarized.  STARTTS indicates the beginning of
    the timespan and ENDTS indicates the end of the timespan.

3.  The following data elements only have meaning when using
    the DESDKDnn file in the DETAIL timespan, in that they
    lose significance once summarization has been performed.
    These data elements should only be referenced when using
    the DESDKDnn file in the DETAIL timespan.

     DEXVOLSR  -  Volume Serial Number
