Discovered this when I joined channel on EFnet. The channel creation date is not printed because it is '0'.
Tested in 7.75 and 7.75.1434.
Code to replicate the issue:
alias chan_creation_date_bug {
.parseline -qit : $+ $server 324 $me #example +nst
; This next line does not print anything in the status window.
.parseline -qit : $+ $server 329 $me #example 0
.parseline -qit : $+ $server 324 $me #channel +nst
; This prints " #channel created on Wed Dec 31 19:00:01 1969 ".
.parseline -qit : $+ $server 329 $me #channel 1
}
