I need to get 12 hours ago from the current date time in date time format. After some searching i have the ability to get one day ago (below) however i would like to just specify 12 hours ago.

Example:
current datetime is 2016-04-19 21:00
then get variable for 2016-04-19 09:00

Example:
current datetime is 2016-04-19 10:00
then get variable for 2016-04-18 22:00

-*this is what i have for one day ago from current datetime, i'm not sure if i can build on it?
-SET &CURR_DT_RAW=HCNVRT(HGETC(20,'HYYMDS'),'(HYYMDS)',20,'A20');
-SET &CURR_DT=HCNVRT(HADD(HGETC(20,'HYYMDS'),'DAY',-1,8,'HYYMDS'),'(HYYMDS)',20,'A20');

-SET &CURR_DT_ALPHA=HCNVRT(&CURR_DT_RAW,'(H14)',14,'A14');
-TYPE &CURR_DT_ALPHA
