Convert numeric variable into SAS time variable

mealie — Thu, 18 Sep 2014 12:54:10 GMT

Hi all,

this is probably an easy one but today my brain is not working.

I have the numeric variable time with e.g. the values 12, 15, 18, ... . Those values should be converted to a SAS time format representing the clock time e.g. 12:00, 15:00, 18:00.

Could you help me to figure out the code?

Thanks a lot

Mealie

get those brains on, I hope there is an on/off switch....
Time and dates are numerics they are nice presented by SAS formats. The only thing I could make up is you are having some number that is in hours.
60 minutes in an hour with 60 seconds and you get the time in seconds. That is the SAS standard of time measurement.

Hi,

your_new_time_variable=hms(your_number_variable,0,0);

The SAS function HMS looks like what you need. The 3 arguments are hour, minute, and second. Just use 0 for minute and second. You may need to format the resulting number in your favorite time format.

data _null_;

ref = hms(13, 0, 0);

put ref /

ref time.;

run;
