Hi virux,

Is it possible that the difference is in the SQL dialect of
the databases?

That is; data type DATE is actually a timestamp (64bit
value) in dialect 1, but it is a date (32bit value) in d3.

Your example from the problem database seems to indicate
that it may be a dialect 1 database (it is showing a time
part for the field, even if it is zero).
