gollark: But... emoji prefixes?
gollark: Okay, fine, I'll implement hexadecimal notation maybe.
gollark: So it *seems* like python datetimes are evil/bad and have significant range limits.
gollark: I have no idea how to deal with this.
gollark: I guess I MAY NOT be able to implement galactic years without SIGNIFICANT work?
