A way to reorder posts?

Not sure if this is the right place for this query but it was pointed out to me in reply to a topic I recently created. As I stated:

I’ve got a few dozen comments that I’m manually importing (we’re talking copying and pasting into the comment box) from Commentics to Discourse. Supposing a previous user from Commentics has set up an account with my new Discourse install I discovered that I can change ownership of the comment from me (as the copier and paster) to said user. What I’m wondering is, now that I’ve done that is it also possible to change the timestamp of said comments in a similar way to how it’s possible to change the timestamp of a topic? If not, would it be possible via some non-GUI method?
