To be honest Quote is something that I regret ever being included in UWS - it is difficult for a service to give a good quote and difficult for a client to take any action on any quote given (especially as it is optional). I would be tempted towards trying to drop it in any future version, although changing to seconds would be more sensible and then the test of “potential success” would be against the execution duration rather than the destruction time - see https://volute.googlecode.com/svn/trunk/projects/grid/uws/doc/UWS.html#Quote
