gollark: Kit was basically just *guessing* what would work and reading the docs without understanding the horrors of ABR.

gollark: I'll test it myself, yes, but you'll at least have mostly working code.

gollark: Yes, but you can actually test yours so I won't have to essentially do all the work myself.

gollark: R. Danny has a much more complex algorithm for accurate timing. PRs welcome!

gollark: Reminders with a due time less than or equal to the current time but which are not yet flagged as expired or failed.
