3rd set of output, changing the session timezone setting (as opposed to has now effect on the 'timestamp' case because it's always returned by PG as is, and interpreted by the JDBC driver in the JVM's zone.Everything works in the 'with timezone' field, because PG returns a zone offset along with the value so the JDBC driver recovers the correct millis instant. 2nd set of output, if the default TZ of the reading application is different from the one in effect when the value is written, you end up with the same 'local' time string, but the actual millis instant this represents is wrong.With JDBC, everything behaves essentially the same way: The 'timestamp' value is read back correctly if the default TZ of the reading application instance matches the default TZ of the application that wrote it (first set of output from the Java code).The 'with zone' value is stored in UTC and treated as an actual instant on the time line, and is display in whatever zone is set in the session.Looking at the psql output first, the 'timestamp' value is stored as a local time exactly how the application that inserted it supplied the value, it's is not shown with a timestamp, and the session timezone settings doesn't affect what's displayed.info ( 'Driver version='', ts2s ( result3. timestamp with time zone' seems to have the semantics of (3) in Oracle and Sybase and (2) in Postgres for example.

joda LocalDateTime), (2) a timeline instant (, ), and (3) a timeline instant with a zone that is stored (, joda DateTime), or equivalently a combination of 1 and 2. Essentially I can think of three conceptual types that might map differently for each DB: (1) A 'human' date/time (i.e. Maybe this could be delegated to the DatabasePlatform, as what different DBs support seems to be quite different in this area. The ability to configure what DB types the various time types map to globally.This would mean I can tell the DB connection to use UTC without having to worry about the default JVM timezone. It would be nice to be able to configure set default TimeZone on the EbeanServer (or maybe even on a transaction), such that calls ebean makes to tTimestamp() and ResultSet.getTimestamp() will use the variant with an explicit Calendar to pass in that time zone.but everyone out there has logical models with 'timestamp' in them (and those map to timestamptz). It might be nice for the logical model to have 'timestamptz' and 'timestamp local'. This is the source of the reason why works in create-all.sql ddl generation but not really via DB migrations. Right now logical 'timestamp' pretty much translates to 'timestamp with timezone'. Now the issue as I currently see it is that ideally we have a distinction between 'timestamp' and 'timestamp with timezone'. We have these 'logical types' so that we can generate multi-platform DDL of the same logical model/diff etc. With our DB migrations we have 'logical types' and then 'platform specific types'.įor example we can have logical type like json(1000) which might translate into varchar(1000) on H2 and JSON on PG. FYI: I am still pondering the approach here.
