Revert "Merge pull request #6344"

This commit needs to be reverted because it introduces difficulties when
using sqlite3 in development and other databases in production. This
happens because when you create time column in sqlite3, it's dumped as
datetime in schema.rb file.

This reverts commit 57d534ee9e441d078fcc161c0c78ebaa5aacd736, reversing
changes made to 20f049fb50daee0c5e5a69b55b529af5737e8e3f.
