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?

All to do with accurate rise-time and decay of the electronics without overhang, ringing, or harmonic distortion.
I was doing some tube rolling. I had a bunch in the phono pre and it sounded a little clearer on the night. Few days later, the sound wasn't great. Played an album, "Friends - Manifest!" Not great. Flat, musically all over the place. Put tubes back. Lots better. Everything snapped into focus including timing.
