Understanding how Spikeinterface handles recording times.

I always thought that SI was essentially time-agnostic and computed times on the fly based on sample number and sampling rate. However I had the same experience as @yger when reading this thread and was surprised time information is tracked.

I just seen this docs page which introduces the concept which is great, I had not seen it before. However it might still be useful to flesh it out a bit and add what happens in certain scenarios e.g. 1) slicing recording 2) concatenate recording 3) appending / concatenating segments.

I'd be happy to do this ASAP (just (hopefully 🤞 ) finishing off an unrelated project and will have more time for ephys). But I thought I'd get the ball rolling here in case there are other cases I had not considered.

Start with the Handle Times documentation page linked in the issue and review the existing explanation of recording times. Expand it to cover slicing recordings, concatenating recordings, and appending or concatenating segments, with the documentation clearly explaining what happens in each scenario.
