ddscut  --  cut out a time interval of telemetry data

USAGE:

 ddscut [-b <beginning>] [-e <end>] [-x] [list] | ...

 The program reads telemetry raw data from files given in list (default stdin),
 compares each packet's time stamp with the specified time interval, and 
 writes only those packets to stdout whose time stamps fall into this interval.

 If the modifier '-x' is set, the mode of operation is inverted: only packets
 whose time stamps do not fall into the specified time period are written to 
 stdout. Thus, the given time interval is excluded from the data.

 In both cases, the time interval is inclusive, i.e., the time <beginning>
 and <end> belong to the time interval that is cut out or excluded.

 Note that a given end time will be increased by one block period of
 5.152222 seconds to ensure that the complete data of the selected time
 interval will be written.

OPTIONS:

  -b    let the string <beginning> specify the beginning of the time interval.

  -e    let the string <end> specify the end of the time interval.

      The following formats may be used for these strings:

      If the string contains the letter 'T', it will be interpreted as 
        an ISO time string like '1994-09-01T12:00:04.012Z'.
      If the date is omitted, i.e. the string starts with a 'T', the date
        is being adopted from the time stamp of the first data package.
      If the string does not contain any 'T', it will be interpreted as
        seconds of the UNIX epoch, like '778420804.012443596'.

  -x     switch to `excluding' mode.

  -V     print the version number on stdout, then exit.
