How long is the flight from Sacramento to Paris?

There don't appear to be any non-stop flights from Sacramento, CA (SMF) to Paris (CDG). The non-stop flight from San Fransisco (SFO) is 10h30m onboard Air France's B747 and the non-stop return to SFO is about 11h15m. To depart from Sacramento would require a stop and a connecting flight. Various airlines do provide this service, but use different cities to connect. The length of any stop-over would obviously change the overall travel time. Connecting flights range from about 13h30m to 21h+.
