And put the last price in to the interval.

 

date

time

price

20071025

13:57:30

100.312

20071025

15:37:30

100.064

20071026

11:50:04

100.05

20071026

17:18:09

99.992

20071027

17:12:09

99.998

 

I try use 

TIME30=intnx("Hour24.15", time, 0, "E");

 

But, I like to get the following dataset from the raw dataset.

20071025 13:59:59 100.312

20071026 13:59:59 100.05

20071027 13:59:59 99.992

20071028 13:59:59 99.998

'hour24.15' is right, but you need to apply it to datetime values, not just time values:

 

data have;
input date yymmdd8. time :time8.0 price;
format date date9. time time8.0;
datalines; 
20071025 13:57:30 100.312
20071025 15:37:30 100.064
20071026 11:50:04 100.05
20071026 17:18:09 99.992
20071027 17:12:09 99.998
run;


data need/view=need;
  set have;
  index_dt=dhms(date,0,0,0)+time; 
  index_dt=intnx('hour24.15',index_dt,0,'e'); 
  format index_dt datetime20.;
run;

data want (drop=index_dt); 
  set need;
  by index_dt;
  if last.index_dt;
  time=timepart(index_dt);
run;
--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets
