Extracting EPOCH value from timestamp without timezone in PostgreSQL

Question

I am getting the following error running this PostgreSQL query. Can anyone tell me how to correct this query?

SQL error:

ERROR:  syntax error at or near "fitacf_data"
LINE 1: ...fitacf_data.num_pts, EXTRACT(EPOCH FROM TIMESTAMP fitacf_dat...
                                                             ^

SELECT fitacf_data.file_date, fitacf_data.num_pts, EXTRACT(EPOCH FROM TIMESTAMP fitacf_data.time), fitacf_data.stcode FROM fitacf_data WHERE fitacf_data.file_date BETWEEN '2017-04-14 00:00:00' AND '2017-04-14 23:59:59' AND fitacf_data.stcode = 'pgr';

If fitacf_data.time already is a timestamp leave the TIMESTAMP keyword away, that's for literals.

...
EXTRACT(EPOCH FROM fitacf_data.time)
...
