Actual time of takeoff and landing

What is the difference between the times posted for pushback at the gate and takeoff - why are they the same time? Aren’t pushback and takeoff different?

And when a plane arrives - the difference between landing and gate arrival? Why are they the same time? Shouldn’t landing on the runway and then arrival at the gate be different?

Thanks. Very confusing.

At some airports (e.g. ELP and LAX) the end of the runway is fairly close to the gate so there’s not much time difference. In most cases there is several to many minutes’ difference between gate time and takeoff time.

Can you give examples? If you are referring to the times shown in an airline’s schedule then you will always see gate times.

Here is the example that prompted my question. Thanks.

Non-USA flight. I wouldn’t relay on the averages for those. In fact, I don’t relay on the averages for domestic flights either.
