sf: set common timeouts in seconds, not milliseconds
Since timeouts are only hit when there is a problem in the system, we don't want to prematurely timeout on a functioning setup. Thus having low timeouts (in milliseconds) doesn't gain us anything in the production case, but rather increases likely hood of causing problems where none otherwise exist.
