Revision:	1241
Committed:	Thu Sep 29 20:26:09 2011 UTC (15 years ago) by michael
Content type:	text/x-csrc
Original Path:	*ircd-hybrid-8/modules/m_trace.c*
File size:	12765 byte(s)
Log Message:	- move firsttime, since, and lasttime Client struct members to LocalUser struct - m_watch.c: show_watch() now properly reports signon times. This also fixes an invalid signon time of zero for remote clients.
