TIMESTAMP stores values as year, month, day, hour, minute, second, and fractional seconds. Module time is providing various time related functions. They said it was stored as a number and that in order to not expire to early (like UNIX time) the storage would, over time, sacrifice sub-second precision to extend the date range. Unfortunately the difference between t1 and t2 is limited for the result to be right. TheTIMESTAMP data type is useful for storing precise time values, such as in applications that must track event order. If we need to store both date and time information in a database, we have TIMESTAMP datatype which, unlike DATE datatype, can store the time informtion. I would like to create a diff column in hours so have been trying it between systimestamp and the statusdate column cast as timestamp. to see whether any timestamps have been included and handle them respectively.
