 @jorisvandenbossche I am fine with merging this before #15998 (or after). lmk. Fixed the comments (apart from import clean-up, can do later a PR)

Would like to get this in before I have to rebase again (it was a rather painful rebase :-))

the tseries.plotting (also tseries.converter is kept as a shim) question, can maybe deal with that when moving/reorganizing the tseries module. > Would like to get this in before I have to rebase again (it was a rather painful rebase :-))

merge as soon as you are ready.

> the tseries.plotting (also tseries.converter is kept as a shim) question, can maybe deal with that when moving/reorganizing the tseries module.

sure (though I would deprecate those modules as you moved them). can do as a followup though. ready to merge? When it is green, yes thanks! and thanks @sinhrks for the original work!
