5.3.2.3 Usage Considerations

Special considerations or techniques related to using the
SCPLCA file are provided below.

1.  The following data element in the SCPLCA file has meaning
    only in the DETAIL timespan; it loses significance once
    summarization has been performed.  This data element
    should only be referenced when using the SCPLCAnn file in
    the DETAIL timespan.

    CYCLETM  - Sampling Time Cycle Length

2.  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; they should not be used in
    those cases.

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

3.  ENDTS and STARTTS, when appearing in the DAYS, WEEKS, or
    MONTHS timespans, bound the span of time over which the
    data has been summarized.  STARTTS is the lowest date and
    time, and ENDTS is the highest date and time for the data
    summarized.  These data elements have different meanings
    when used in the DETAIL timespan versus the DAYS, WEEKS,
    and MONTHS timespans.  Their purpose in DETAIL is
    described below:

    o  STARTTS represents RMF recording interval start time.
    o  ENDTS represents RMF recording interval end time.
