See file glpk/examples/glpsol.c, lines 1429-1430:

      xprintf("Time used:   %.1f secs\n", glp_difftime(glp_time(),
         start));

Please note, however, that a small solution time (less than a second)
displayed by glpsol may be inappropriate for your purpose. In such
cases I'd recommend just to say that the solution time was less than a
second on a such-and-such processor.
