Sony Ericsson :: W995 / Download Application To Have Timed Profiles?

Does anybody know a way or an application I can download that would allow me to have timed profiles on my SE phone (W995)? I used to have a Nokia phone where you could have a timed profile where you could set it to silent until say 5pm when I left work. This was handy because I usually forget to change the profile on my phone. It was also handy when going to see a movie, I could set it to go back to the normal profile about 2 1/2 hours after the movie started. I know it's simple enough to change it yourself but I always forget to change it and end up kicking myself when it's on silent and I miss a few calls or texts.
