PostgreSQL从来不会在确定文字串的类型之前检查其内容,因此会把上面两个都看做是 timestamp without time zone。因此要保证把上面的文字当作timestamp with time zone看待, 就要给它正确的显式类型: TIMESTAMP WITH TIME ZONE '2004-10-19 10:23:54+02' 1. 如果一个文字
select timestamp with time zone 'epoch' + 1369755555 * interval '1 second'; 时间戳转成epoch值 select extract(epoch from now()); 具体时间戳转换为utc(即epoch) select extract(epoch from timestamp without time zone '1970-01-01 01:00:00'); ...
