There was a rule in 3.5 that let you take 10 if you had all the time in the world to redo the skill, time also effected the dc if I remember correctly. Say you had a golem rushing twords you and you need that door unlocked asap, pretty sure the dc goes up for trying to do something in a hurry...don't quote me on that last one not sure.
