SAS timestamp from scientific notation to yyyy / mm / dd hh: mm: ss

Question

Problem:

My timestamp is displayed in scientific notation. I would like to display a column without scientific notation and create a second column formatted as a long date, yyyy / mm / dd hh: mm: ss.

Steps taken:

I have already converted a column from the time of the UNIX Epoch (1960) timestamp to the SAS (1970) timestamp. But scientific notation persists. I tried the date20. also does not do the trick.

    format timestamp date9.;
run;

Results:
