Amp "timing" ?


I was reading someone raving about the impeccable "timing" of their high-end amp this morning.  I have heard this term tossed around several times recently in my dive back into highish-end audio. 

Can someone please explain what is meant by this term?  Is it snake-oil or confirmation bias?  I just don't understand how a human  can hear  a timing difference of a soundwave unless it's a 2nd+ order reflection.  

Thoughts?

A good musician will play on, behind, or ahead of the beat, resulting in the "feel" of a musical presentation...that’s timing, and if my hifi rig does any of those things on its own I’ll assume I’ve lost my mind.
I was trapped into a "presentation" (in the late 80s maybe) at a stereo shop of why a Linn LP12 table, when compared to a Denon direct drive table, was more  rhythmically accurate...it wasn't.

Regardless of your opinion about the turntables, it easy to see how a turntable could have an effect on timing. An amplifier, not so much.
