But re-read my post (and excuse my horrible English), I say that would help a lot if the microseconds part of a timestamp will be zero padded to a minimum length of 5 or 6 digits. Like: "then most databases can take 2004-07-10 12:59:59.123 as 2004-07-10 12:59:59.123000 " This behavior help is cross (vendor) database operations . Dario. >On Sat, 2004-07-10 at 13:20, Dario V.
