Time Scheduled syncing app?

Are there any apps out there that would allow me to have both gmail and exchange switch from "as mail arrives" to "manual" certain times of the day?

For instance, I sit in front of my work computer most of the day and don't require immediate email to my phone, same with gmail.. So from say 8-5pm I don't really need instant mail. Also, from say 11pm - 6am I also don't need instant mail since I'm sleeping

it would be important that this would be controlled by days (for instance, I would like to be able to schedule the instant mail off on Monday, Tuesday, Thursday and Friday from 8am - 5pm.

TIA for any suggestions,

Thanks guys...

I installed the lite version of settings Profiles, and did some basic setup. I can't turn off syncing in the lite version but I can test the location based profile changing. that actually works better than time based... On days I'm not at work I'd just assume keep things on.

Thanks again!! Hopefully settings profiles works out, and I'll buy the full version.
