Seems like a bug: the departure and arrival times are swapped. So it arrives Nice at 11:40am and departs 2:20pm which is indeed 2:40h layover. AF 661 departs OPT at 10:10am and arrives Nice at 11:40am.
You can't really fly backwards in time :-)

As someone whoβs been working with Skyscanner data for Flightbot (https://flightbot.com), I can assure you that the data from Skyscanner (and other sites for that matter) are often flat out wrong. Their data is only as good as their sources.
Searching for this itinerary (Bucharest through Nice), this itinerary is totally flubbed. The first flight should be 10:10 to 11:40, not 11:40 to 10:10: https://www.google.com/flights#flt=OTP.NCE.2019-01-03.OTPNCE0RO401;c:USD;e:1;sd:1;t:f;tt:o;sp:.USD.11965; similarly, the other flightsβ times are all reversed. Even flight search engines make mistakes!
