how to convernt character variable into datetime format

I have the character format value for one variable:

Date
2010-05-05 00:00:00

But I want to change it into datetime format. How can I do it?

I tried:

date_new = input(Date, YYMMDD10.) -- But this wont give me time information

I also tired:

date_new = input(Date, Datetime.) -- but failed...

Anyone can help me on it?

Thanks,

You can try this:
data a;
   input datetime $30.;
   datalines;
2010-05-05 00:00:00
;
run;

data b;
   set scan(datetime,2," ");
   format date mmddyy10. time TIME.;
   date=input(scan(datetime,1," "),yymmdd10.);
   time=input(scan(datetime,2," "),TIME.);
run;
