You should have a man page that states

"-t sec
Tell init(8) to wait sec seconds between sending processes the warning and the kill signal, before changing to another runlevel."

When the shutdown occurs, a program called init must kill running processes. To do this it first does the equivalent of a "kill -15 pid" and if that doesn't work, it will do the equivalent of a "kill -9 pid". The -t is affecting how long init waits between the two kills. The default is 5 seconds. So a "-t 120" might take longer to complete the shutdown. But if the first kill works, init will never try the second kill. In that case, the -t could have no effect at all.

KILL(1) 						     Linux Programmer's Manual							   KILL(1)

NAME
kill - terminate a process SYNOPSIS
kill [ -s signal | -p ] [ -a ] [ -- ] pid ... kill -l [ signal ] DESCRIPTION
The command kill sends the specified signal to the specified process or process group. If no signal is specified, the TERM signal is sent. The TERM signal will kill processes which do not catch this signal. For other processes, it may be necessary to use the KILL (9) signal, since this signal cannot be caught. Most modern shells have a builtin kill function, with a usage rather similar to that of the command described here. The `-a' and `-p' options, and the possibility to specify pids by command name is a local extension. OPTIONS
pid... Specify the list of processes that kill should signal. Each pid can be one of five things: n where n is larger than 0. The process with pid n will be signaled. 0 All processes in the current process group are signaled. -1 All processes with pid larger than 1 will be signaled. -n where n is larger than 1. All processes in process group n are signaled. When an argument of the form `-n' is given, and it is meant to denote a process group, either the signal must be specified first, or the argument must be preceded by a `--' option, otherwise it will be taken as the signal to send. commandname All processes invoked using that name will be signaled. -s signal Specify the signal to send. The signal may be given as a signal name or number. -l Print a list of signal names. These are found in /usr/include/linux/signal.h -a Do not restrict the commandname-to-pid conversion to processes with the same uid as the present process. -p Specify that kill should only print the process id (pid) of the named processes, and not send any signals. SEE ALSO
bash(1), tcsh(1), kill(2), sigvec(2), signal(7) AUTHOR
Taken from BSD 4.4. The ability to translate process names to process ids was added by Salvatore Valente <svalente@mit.edu>. Linux Utilities 14 October 1994 KILL(1)
