Shorthand for epoch

Is there a shorthand for the epoch instead of having to type '1970-1-1 00:00:00' all the time?

It is surprisingly 'epoch'

select 'epoch'::timestamp;
timestamp
1970-01-01 00:00:00
(1 row)

select TIMESTAMP 'epoch';
timestamp
1970-01-01 00:00:00
(1 row)

Special date/time inputs are described in the section 8.5.1.4 here:
