Why is using EXTRACT EPOCH giving the same result for two different timestamp inputs?

I am running an EPOCH with different dates. But both are giving me same output. Why?

select EXTRACT(EPOCH FROM AGE('2016-04-26 00:00:00','2016-03-27 00:00:00'));

select EXTRACT(EPOCH FROM AGE('2016-04-26 00:00:00','2016-03-26 00:00:00'));

Can anyone explain?
