During line ops F/Os only log ICUS or co-pilot, S/Os only ever log co-pilot. The whole sector is logged whether on the flight deck or not. The only one who logs command time is the Captain.

To hold a command endorsement a F/O has to fly to the aeroplane limits and charted approach minima in the simulator but is restricted during line operations as far as crosswind strength and departure and arrival weather conditions.
