octave:1> help strptime 
strptime is the dynamically-linked function from the file
/usr/lib/octave/2.1.46/oct/i386-pc-linux-gnu/strptime.oct

 - Loadable Function: [TM_STRUCT, NCHARS] = strptime (STR, FMT)
     Convert the string STR to a time structure under the control of
     the format FMT.

Works similar to the C function of the same name.  The format is
similar to that used by strftime.

  octave:7> t = strptime ("03/12/2003 22:12:28.209", "%m/%d/%Y %X")
  t =
  {
    hour = 22
    isdst = 0
    mday = 12
    min = 12
    mon = 2
    sec = 28
    usec = 0
    wday = 3
    yday = 70
    year = 103
    zone = 
  }

  octave:8> strftime ("%D %X", t)
  ans = 03/12/03 22:12:28
