my psyBNC is working fine but i have one question:
if i'm using "playtrafficlog last" i get the logs of the corresponding channels.
But there is one problem: the timestamps are from NOW, so if sth is posted 6hours ago my timestamp shows not 6:30 but 12:30 [now].
Not really, those timestamps you see are generated by your irc client, not the server (or psybnc). As they're sent when the client connects, they're then timestamped "now".
