Here's a quickie example:

use strict;
use warnings;

while (my $line = <DATA>) {
    chomp;
    print "INPUT LINE: $line\n";

    # Read all the times from the line and place into array
    my @times = ($line=~m/[-+0-9.E]+/g);

    # Print the values
    print $_*1000, "\n" for @times;
}

__DATA__
  2.83506E+03  2.83697E+03  2.83911E+03
  2.84117E+03  2.84331E+03  2.84544E+03
  2.84750E+03  2.84958E+03  2.85172E+03
  2.85383E+03  2.85588E+03  2.85804E+03

This gives me:
