    Here's how I would do it with saclst in bash.

    kztime=`saclst kztime f sacfile_name | gawk '{print $2}'`

    Dear SAC Users,

    I have recently faced with a problem when
    processing on the data header of one binary sac data file.
    To sum it up, when I read and want to list header info, I have got the following type of
    error and


    the rest :

     ERROR  907: Bad time field entry detected: 22 8 26 1432
           NPTS =
    360000
              B = 0.000000e+00
              E =
    3.599990e+03
         IFTYPE = TIME SERIES FILE
     ERROR    0:      LEVEN =
    TRUE


          DELTA = 1.000000e-02
           IDEP = VELOCITY (NM/SEC)
        
    DEPMIN = 5.701760e+05
         DEPMAX = 5.752970e+05
     ERROR    0:     DEPMEN =
    5.730679e+05
         KZDATE = MAR 30 (089), 2007
         IZTYPE = BEGIN
    TIME


          KSTNM = IPA2
          CMPAZ = 9.000000e+01
     ERROR   
    0:     CMPINC = 9.000000e+01

    ............................................................ .......

    Here at
    that point KZTIME information is important for my processing and most probably due


    to that sort of error I can't see and grep it later on. Is there anyone who has idea how to get
    the data header fixed or any trick on how to get
    KZTIME information despite this error?

    I appreciate any suggestion on this matter ...





    best regards

      To follow up:

      The values from kztime should be:
      0 <= hour <= 24
      0 <= min <= 59
      0 <= sec <= 59
      0 <= msec <= 999

      ERROR 907: Bad time field entry detected: 22 8 26 1432

      From your output the hour = 22, min = 8, sec = 26 and the msec = 1432
      millisecond (1432) is outside of the allowed range, so the 907 Error
      is occurring.
      The output for the error message *should*, and will be better in the
      future.
      I believe your seconds should be at 27 and msec should be 432.

      You might also encounter this error when reading a SEGY file with a
      illegal time value.
