Adding up different time intervals

Ive attached a file of my code.

What im trying to do is add up all the number in the absorder column for each given 15min window under then NZtimeentereed15 column.

 

Ie for the first 15min window it should return 13. second 15min window( ie 30min) it should return 3.

23 for the 45th min.

 

I have over 700,000 observations

 

all help would be great.

Re: Adding up different time intervals

Use proc means or a SQL query. 

Sum variable of interest. 

If SQL group by time variable. Or if proc means include time variable as Class or By variable. Number of observations doesn't matter.

Re: Adding up different time intervals

Proc SQL;
Create table want as
Select time, sum(variable) as total
From have
Group by time
Order by time;
Quit;

Proc means data=have noprint nway;
Class time;
Output out=want2 sum(variable)=total;
run;
