It leaves the problem of dealing with skill challenges that aren't in any way combat-related, though.
I don't see why time can't be an issue outside of combat. For example:
- The PCs are trapped in a room that's filling with water.
- The PCs investigate a plot to assassinate a prince before the assassination takes place.
- The PCs try and revive a dying man before he passes into the beyond.
- The PCs must track down their prey before the weather washes away traces of their passage.
Skill Challenges should be called for when situations are tense. A DM should spend as much time designing a Skill Challenge and making it exciting as they do a Combat Encounter.
Also, time is not the only way to add pressure. What about adding in choices where you can gamble greater success for greater risk? What about where you can choose to take a failure for some positive end?
For example, in a "Creep Up to the Moathouse" Skill Challenge I created for Hommlet, I allowed Nature successes to be used toward the Skill Challenge or to reduce the number of Giant Frogs alerted by the PCs passage (which were a seperate threat). The outcome became a juggle of:
- Sneaking up on the Moathouse sans Giant Frogs
- Sneaking up on the Moathouse being beset by Giant Frogs
- Alerting the bandits in the Moathouse sans Giant Frogs
- Alerting the bandits in the Moathouse beset by Giant Frogs
There is a lot more room in SKill Challenges than in combat. DOn't expect it to fill itself. Be creative.
