The ability to cut time comes from the Susanoo unit itself, as that ability is the source of it's nickname Tokigiri (time cutter). A blade that can kill time might have been a direct reference to Susanoo itself (or to the Time Killer), as Susanoo acts as the Amaterasu's Blade, in similar manner as Nu acts as the Izanami no Tsurugi (Sword of Izanami). When Terumi takes the form of the Dark Susanoo, he literally calls himself Kami no Tsurugi (Sword of God).

In a way, what the Imperator was saying was not that only that the time killer is ineffective, but the Susanoo unit itself. Essentially, there was (probably) a double meaning behind to what Iznami was saying, not only that time killer is moot, but the Susanoo's ability to cut/alter time is meaningless before someone who no longer has "time"/whose "time" ended long ago.

As to if he actually used it... it is hard to say. While Ragna certainly gave him enough time to prepare it, the name "Time Killer" is never used, but Hakuman is certainly surprised that nothing happened. As Rachel confirmed that her body, the host that is, can be destroyed, it would indicate that Hakumen's slash wasn't a normal slash, but one that can at least cut or kill time.
