timestamp

Hi!
I would to change the timestamp of a file to 12 FEB 2007 00:00 on sun solaris 10.
I used:

touch filename -t 200702120000

but doesn' t work!

Wrong order.

touch -t 200702120000 filename

It's the same:

touch -t 200702120000 1.txt
usage: touch [-amcf] file ...

you are using ucb touch, try /usr/bin/touch

great!
Thnks a lot!
