-mis'li gecmis zaman or "inferential past tense" is "inferential mood" and "past tense".

Essentially old school people categorised tenses out of thin air; and modern linguists define tenses as "time reference",mood as "modality signalling" that is "relationship to the reality / truth" and aspect as "expression of how something extends over time". So aspect doesn't apply here.

So -mis'li gecmis zaman is a tense and a mood. Sometimes.

Sometimes it is something altogether different such as mirativity (https://en.wikipedia.org/wiki/Mirativity).

PS: I have to say, I'm surprised your handle in HN isn't @ssg :)
