Do you understand that visual tools such as IB Manager that you are using apply a "picture" to date and time types? The actual *data* are just numbers.

-- For TIMESTAMP type, there are two numbers: one number that records the number of days since "date zero" + another number that records the number of milliseconds (or thousandths of seconds, depending on config.) since midnight.
-- For DATE type, there is just the one number that records the number of days since "date zero"
-- For TIME type, there is just the one number that records the number of milliseconds (or thousandths of seconds, depending on config.) since midnight.

So, what Thomas means is, does IB Manager always display DATE type data as though it were TIMESTAMP data, i.e., displaying a date with 00:00:00 in the time?

You could check this by using IB Manager to view a table that is storing a DATE column...
