" C: Searching based on channel creation time, via the "C<val" and "C>val" modifiers to search for a channel creation time that is higher or lower than val." -- <https://modern.ircdocs.horse/#elist-parameter> -- https://datatracker.ietf.org/doc/html/draft-hardy-irc-isupport-00#section-4.8

Unfortunately, this is ambiguous, because "val" is a time delta (in minutes), not a timestamp.

On InspIRCd and Charybdis/Solanum, "C<val" is interpreted as "the channel was created less than <val> minutes ago

On UnrealIRCd, Plexus, and Hybrid, it is interpreted as "the channel's creation time is a timestamp lower than <val> minutes ago" (ie. the exact opposite)

LIST on a nonexistent channel does not send an error

When a channel exists, LIST should get it in a reply.
