Oracle's DATE includes a time part as well.

So simply use a timestamp in PostgreSQL and everything should be fine.

Yes, but how can I copy Oracle's DATE into PostgreSQL's timestamp?

(I realize that this more an Oracle question, sorry)

What format string should I take for Oracle's to_date() function,
I don't see a format string to get epoch seconds there

I have no idea what you are doing in PHP, but why don't you simply generate a valid date/time literal for Postgres using the to_char() function?

Something like

SELECT 'TIMESTAMP '''||to_char(QDATETIME, 'YYYY-MM-DD HH24:MI:SS')||''''
FROM qtrack;

That literal can directly be used in an INSERT statement for PostgreSQL
