curious about gather system stats, or I'm wrong

Hi.

exec DBMS_STATS.GATHER_SYSTEM_STATS(gathering_mode=>'INTERVAL' interval=>1/24);
 Or this is a wrong way to get system statistics?, and is better to gather system statistics only in the moment.  

I found this interesting
interval is not set in minutes as documentation says, it is in days, but the interesting is I can get system after the period (note the dstart and dstop)
