$ial(nick/mask,N).ctime returns $ctime format when user appeared on the network

Go get that, a /whois must be done on the nick.

nope.

simple analog:
raw 366:*: {
var %i = $nick($2,0)
while (%i) {
var %nick = $nick($2,%i), %i = %i - 1
hadd -m $+(ial.ctime.,$cid) %nick $ctime
}
}
+ controls other events JOIN/PART/NICK/QUIT for add and delete $nick's $ctime

It's like $ial, no need to /whois. This works if server sends nick!user@host in /names or user execute /who #channel.

Just I want get $ctime from $ial

a user is added to the IAL when his address is first revealed, not his nickname. while there isn't currently a very comfortable way to detect when a user is added to the IAL (there's a few events to consider, or perhaps /debug to an alias), i don't think that occurrence is meaningful enough for the proposed property to be considered a useful addition.
