Unless you had some other use for the intermediate variables, I'd replace
$time = $1;
$tid = $2;
$status = $3;
$trname = $4;
$tramount = $5;
$hash{$2}->[0] = $status;
$hash{$2}->[1] = $time;
$hash{$2}->[2] = $trname;
$hash{$2}->[3] = $tramount;
with
$hash{$2}{status} = $3;
$hash{$2}{time} = $1;
$hash{$2}{trname} = $4;
$hash{$2}{tramount} = $5;
It's slightly shorter, and slightly more readable. (That is, it prevents you from asking 'What does subscript 2 stand for again?'.)
