    time in accordance, with beg=0 for the latest file and beg<0 for
    the others. Then you should write the seismograms on temporary files
    a read them again after setting the cut range from zero to the desired time.


    r file1.sac file2.sac
    write change .sac .cut
    cut 0 1000
    r file1.cut file2.cut
