The RBD snapshot create timestamp required a change on the OSD side to record the timestamp. Therefore, for older clusters or pre-luminous snapshots, there is no way to retrieve a creation timestamp since it just doesn't exist anywhere.

hi,guys
we have much snaps,and we want to clear.
but can not know the create time of these snaps.
I know luminous have this feature default.but for jewel and hammer,have some
hack way to get the create time?or it is just impossible.
Which kind of snapshot are you talking about? Which interface? In a
quick skim of the current tree I don't see anything that's changed
recently in the APIs around these.
