hi, for this test, i'm using hsqldb (1.7.1).. but i'm not quite sure what this would have to do with the jdbc driver itself - in this case, we're only talking about two inserts, there's nothing to be read back from the db... OTOH, the jdk itself (i'm using 1.4.1_01) does silly things when creating new Timestamps( d.getTime() ) - the nanosec portion is different depending on the milliseconds... personally, i wouldn't mind if hibernate totally ignored the nanos, comparing on the millisec precision... never in my life i needed that, and if i would be into that level of detailed measurements, i would probably use my own datatype for that, since the built in java date classes make my eyes twitch uncontrollably...
