Question Understanding shutdown

Hi there,
I start using the function shutdown instead of reboot + poweroff.
But there are some points that are not explained in the man pages.

1) What is the usage of the t swith.
Quote:
shutdown 22:30 'Beware!'
shutdown -t 30 22:30 'Beware!'
Both commands will display the message immediatly on every terminal and shutdown at 22:30. Where is the difference?

2) Can I specify the date/time like in the date command?
Quote:
supernova:~# date
Mon Feb 16 22:33:45 CET 2009
supernova:~# date -d 'now + 1 minute'
Mon Feb 16 22:34:49 CET 2009
supernova:~# shutdown 'now + 1 minute'
Usage: shutdown [-akrhHPfnc] [-t secs] time [warning message]
[...]
supernova:~#
Thanks for your help
Santiago
