How long is the "temporary" account ban from bungie/Halo Reach?

As far as I know, I believe the first time is 24 hours and the second is 1 week.

I have been unable to find anything documented anywhere stating the time frame of the "Temporary" bans based on the offense. My ban was finally lifted 1 week after it was instated. I would venture that this is probably a standard time frame for the first offense of unsportsmanlike conduct.
