Use the appropriate informat to create a sas datetime variable. Then assign the format iso8601dt to the created variable. Job done.

If you can read it in as a TIME instead this becomes fairly easy:

 

data sample;
input year month date time : time.;
format time time.;
cards;
2014 6 10 08:12
2014 6 11 08:16
2014 6 13 08:34
2014 6 14 08:12
2014 6 15 08:19
2014 6 16 08:45
;



data want;
set sample;

time_want = dhms(mdy(month, date, year), 0, 0, time);
format time_want E8601DT.;
time_want_char = put(time_want, E8601DT.);

run;

proc print;run;

If you already have time as character you can convert it using the following and then replacing time in the code above with time_num.

time_num=input(time, time.);
