I would like to calculate difference between two time periods in days Hours, minutes ( how long it takes to complete the task)

for example difference between 12MAY2014:08:20:19:00 and  07MAY2014:08:00:45:00

Please help

Thanks,

data x;
t1 = '12MAY2014:08:20:19.00'dt;
t2 = '07MAY2014:08:00:45.00'dt;
days = int((t1-t2)/'24:00:00't);
time= mod((t1-t2),'24:00:00't); 
format time time8. t1 t2 datetime.;
run;

Subtract the two records will give you the time in seconds. Then you can convert that to minutes/hours with some basic math (ie divide by 60). You can also try formatting using various time formats but because you cross days that might be an issue.

I did subtract the two . However, I like to get the results in Days Hours using format statement or functions?

How would you like that to look? I don't believe there's a standard way to indicate days for duration in standard format.

Take the difference between the two, the result is a number of seconds, then express in the required units:

data _null_;

t1 = '12MAY2014:08:20:19.00'dt;

t2 = '07MAY2014:08:00:45.00'dt;

dt = t1 - t2; /* time expressed in seconds */

dtStr = catx(":", put(dt/(24*60*60),6.0), put(mod(abs(dt),24*60*60),hhmm.));

put dt= dtStr=;

run;

Something like:

data _null_;


t1 = '12MAY2014:08:20:19.00'dt;

t2 = '07MAY2014:08:00:45.00'dt;

howlong = intck('second',t2,t1);

days = datepart(howlong);               /* basically taken from Professional SAS Programming Secrets, dating back to V6.03 and page 366-367     */

partday = timepart(howlong);

put days 3. ':' partday time8.

run;
