I have a time variable and I want to round the observations to the nearest 30 min.
so 2:15:00 for example would be 2:30
5:05:00 would be 5:00:00
5:20:00 would be 5:30:00 and so on. I would appreciate any help.
I'm using base SAS 9.4
data have;
t='5:05:00't;output;
t='5:20:00't;output;
format t time.;
run;
data want;
set have;
roundedtime=round(t,'00:30:00't);
format roundedtime time.;
run;
