I need to write some perl code that will compare line 1 with line 2, then compare line 2 with ilne 3 etc. I tried the following: 
while (my $timeOne = <INPUTFILE>)
{
 my $timeTwo =<INPUTFILE>;
 print OUTPUTFILE "timeOne: $timeOne";
 print OUTPUTFILE "timeTwo: $timeTwo";
 my $result = $timeTwo - $timeOne;
 print OUTPUTFILE "result = $result \n";
}

But this will compare line 1 against line 2 and then line 3 against line 4.
