    Program TEMP was a temporary program written to correct time errors,
    specifically zero time jumps. To do this a record was read. If it had the same
    time as the previous record, the previous record had 18 seconds subtracted from
    it before writing it to an output file. This seemed to match the prevailing
    pattern of time jumps in the file. Zero jumps occured when the hour field
    turned over.
