If we are talking about SQLMODE Oracle, the datatype date will be able to include date 
and time together.
if we are talking about the SQLMODE internal (default), date just includes the date, 
no single bit for time,
the datatype time includes just the time, no single bit for date. The only datatype to 
include both is timestamp.

And as others mentioned before:
the transaction-handling is very inportant. If one task is inserting data, it has 
locks on that data
until commit or (implicit if session stops without explicit commit/rollback) rollback.
Other tasks selecting will come along the data and find a row locked (by the inserter).
With default-isolation-level 1 they are not allowed to see data neither committed nor 
rollbacked,
but just somewhere in the middle of a transaction. The selector therefore waits until 
the lock
is closed (by commit/rollback of the inserter) and there was (by that transaction) a 
decision made
if the data will stay or will be deleted by rollback. Therefore the selecting task 
seems to be locked.
