Time of day Notification volume control?

[bernoulli]

I use the thunderbold as a work phone. I typically have audible notifications for texting and emails during the day. At night I turn the audible notifications for texting and emailing off but leave the ringer on as I can be called out to work at night. Is there a way to automatically turn the notifications off based upon time of day, or is there an application that will do the same?
