Intended use: I want to know whether I actually want to show up to Cassie, or if she's been dead for only 90 minutes so she won't be up for 30 more.
Either hide it in the /arisu command, or maybe make it configurable to be visible in the alarm itself (show last occurrence as well as next one upcoming), or something? That's the best I got.
(This obviously doesn't tell me whether there's a new instance or anything, but it'd eliminate some "false positives".)
