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.
