This command should work similar to the "#repop force" command which will reset the spawn timers for the zone and repop everything including anything that was down due to having a timer left on it.  I haven't tested this code yet, but I am going to test it tonight and verify it works.  I basically just looked at the code for quest::repopzone() and for the command #repop and combined the 2, so I think it should work.  I will report back later after I get the chance to test it.
questmgr.cpp
	Code:
	void QuestManager::clearspawntimers() {
	if(zone)  {
		char errbuf[MYSQL_ERRMSG_SIZE];
		char *query = 0;
		database.RunQuery(query, MakeAnyLenString(&query, "UPDATE spawn2 SET timeleft=0 WHERE zone='%s'",zone->GetShortName()), errbuf);
		safe_delete_array(query);
	}
}
 questmgr.h
	Code:
		void clearspawntimers();
 
perlparser.cpp
	Code:
	XS(XS__clearspawntimers);
XS(XS__clearspawntimers)
{
	dXSARGS;
	if (items != 0)
		Perl_croak(aTHX_ "Usage: clearspawntimers()");
	quest_manager.clearspawntimers();
	XSRETURN_EMPTY;
}
 
	Code:
			newXS(strcpy(buf, "clearspawntimers"), XS__clearspawntimers, file);
 If this doesn't work, I will keep messing with it until I can get it working unless someone else feels like making some suggestions.
