Try the INTNX function.

Or use a time constant.

----------
15   data _null_;
16
17      base = datetime();
18
19      before = base - '00:10:00't;
20      after  = base + '00:10:00't;
21
22      xyz = intnx('minutes', base, 10);
23
24      format base before after xyz datetime.;
25
26      put base= / before= / after= / xyz=;
27
28   run;

BASE=27MAR00:13:24:16
BEFORE=27MAR00:13:14:16
AFTER=27MAR00:13:34:16
XYZ=27MAR00:13:34:00
NOTE: The DATA statement used 0.08 seconds.

Hello again. I have another novice question about time intervals i calculate
my time intervals like this:
sas_beg1=hms(int(beg_tim1/100),mod(beg_tim1,100),0);
sas_end1=hms(int(end_tim1/100),mod(end_tim1,100),0);
dur_min1=intck("min",sas_beg1,sas_end1);

however, i am trying to subtract 10 minutes from sas_beg1 and add ten
minutes to sas_end1. I have tried several different things to modify my
above code but this doesn't work well. Any ideas? Ruben
