It varies depending on device and usage. The battery monitoring on NexusOne happens every ten minutes, so that's the longest you'll see a N1 suspended for. On a G1 or Dream/myTouch you can see 20-30 minutes between wakeups (depending on network issues and background data sync traffic), and if you have background data sync off those devices can sit in suspend for days at a time (unless you receive a phone call or something). In "airplane mode", with no local alarms, a device can easily sit in the lowest power state for a month or so, until the battery finally runs out.
