????

why is "date_format( lastlogin,' %W %l %i %p')" gives funny numbers ?

 

I couldn't figure out why using the same syntax, same script, just different query can lead to different result ?

and the exact same query, when use in a npc, it doesn't bug at all

-	script	kjsdhfkjsdhf	-1,{OnInit:	query_sql "select lastlogin, date_format( lastlogin,' %W %l %i %p') from login where account_id = 2000000", .@time1$, .@time2$;	announce .@time1$ +" "+ .@time2$, 0;}
