field name data type format


[Quoted] DAY		DATE		DD-MON-YY
START		DATE		HH24:MI

if DAY is 04-DEC-97 , START is 08:30
the data type of time1 is CHAR
the data type of time2 is DATE

I write :
[Quoted] time1:=to_char(DAY)||' '||to_char(START); time2:=to_date(time1,'DD-MON-YY HH24:MI');

the time1 will be '04-DEC-97 08:30' ---> it's data type is char

why time2 will be 04-DEC-97 00:00 
                                    	                 ^^^^^^^
WHY??? Please tell me! THANKS! Received on Fri Dec 05 1997 - 00:00:00 CET
