Ok. this question usually come to my mind and always I prefer using millis because I think that is the easiest way to store and get the time in database.
But some of my friends prefer using timestamp.
So I just wanted to know, What is the best practise for storing time in database ?
When choosing between timestamp and millis which one you prefer using and why?
We have a very similar problem. We keep timestamps in numeric form as "epoch nanos" (nanoseconds from 1970-01-01 00:00) We are using PostgreSQL as the database, and I would very much like to use the native type (TIMESTAMP) [1], but PostgreSQL only keeps TIMESTAMP columns to microseconds, not nanoseconds. :-(
Using the native DBMS types allows use of native DBMS time and interval functionality, unless you like doing it yourself.
