Test whether file1 is older than all the others

Usage:  older [-2h-] file1 file2 [ file3 ... ]

   Prints "1" if file1 is older than all the others, otherwise
   prints "0".

Options:

   -2         Two-second granularity for comparing timestamps.
              Timestamps on NTFS have a 100 nanosecond granu-
              larity.  But if the file is copied to a FAT or HPFS
              partition, where the granularity is only in two-
              second increments, the timestamp may be rounded
              up or down, somewhat arbitrarily.  (NT rounds down
              but OS/2 rounds up.)  This option causes any two
              timestamps within any given two-second window
              (endpoints included) to compare equal.
