The following bug has been logged on the website: Bug reference: 12460 Logged by: Alan Edel Email address: adeconsulting@pacbell.net PostgreSQL version: 9.3.5 Operating system: FreeBSD 9.3 Description: 8.3.6 queries using "timestamp" and "timestamptz" casting both give the same result: select extract(epoch from cast('2015/01/07 14:00:00' as timestamp)); date_part ------------ 1420668000 (1 row) select extract(epoch from cast('2015/01/07 14:00:00' as timestamptz)); date_part ------------ 1420668000 (1 row) However, 9.3.5 gives different results, the first one appears to be incorrect: select extract(epoch from cast('2015/01/07 14:00:00' as timestamp)); date_part ------------ 1420639200 (1 row) select extract(epoch from cast('2015/01/07 14:00:00' as timestamptz)); date_part ------------ 1420668000 (1 row)
