Oracle has a default Format Pattern contained in the NLS_TIMESTAMP_FORMAT setting. It is applied when reading a TIMESTAMP value, and no Format Pattern has been used. For an example, please consultThe NLS_DATE_FORMAT Setting, as these two settings have a similar function. Oracle TIMESTAMP WI...

The result is the same value but converted to a TIMESTAMP data type. Similar Functions Some functions which are similar to the TO_TIMESTAMP function are: TO_DATE: This function converts a value into a DATE data type, which is similar, but has no time component. ...
