Why are you using 'system' to write to a file? Have you not heard of Perl's file managing functions? Have you read any documentation about this?

Yes. The ones that come with your Perl distribution.
What OS are you running this on?

What you mean, I'm sure is
open FH, ">>$file_name" or die "can't open '$file_name': $!"; # <<<< outside the loop
foreach ( @main_time )
{
print FH $_;
}
close FH; # <<<<<<<< outside the loopAnd nowadays, the '3-argument' with lexical file handle syntax is suggested:
open my $FH,'>>',$file_name' or die "Can't open $file_name: $!";

Actually, that was the impression I had too. So you might be correct. Maybe the OP will clarify.
