It's the one (from freenode anyway) that tells you where you're connecting from.

2020-02-11Use time_t for save signatureJune McEnroe
It's actually more likely to be 64-bit than size_t anyway, and it eliminates some helper functions. Also don't error when reading an empty save file.

Allows removing a bunch of checks that self.nick is set, and it's what the server usually calls you before registration. Never highlight notices as mentions.
