I suspect that you actually sent the same timestamp string twice, one hour apart, in which case I'd have to call this an application bug. You really need to include the timezone specification in order to have an unambiguous timestamp string. It doesn't have to be UTC as you previously suggested, but it does have to be labeled with the intended zone. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
