Published departure and arrival times are for gate departure and gate arrival. Actual departure/arrival times are dependent upon the individual airline's procedures. Most USA airlines use actual parking brake release for departure and final parking brake "set" for arrival times. You will see significant variations on the latest published arrival time on airport monitors because we (pilots) are guessing what the actual landing time will be and the airline guesses [normally using historical data] on how long it will take to park at the gate after landing. Many, many variables will change the actual times from these guesses.

Definition of times - for airlines... (and crews) -
Block OUT time, time at which airplane is pushed back, or moves.
Takeoff time, time at which power is applied for takeoff.
Landing time, time at which the aircraft lands.
Block IN time, time at which blocks are placed forward/aft of wheels at gate.
The airline schedules are based on block time (Block OUT - Block IN).
ATC and flight plans use takeoff and landing times.
Flight hours for airplanes (maintenance, airplane age) is takeoff to landing.
Flight hours for crew (flight pay if applicable) is Block OUT to Block IN.
