Gitlab::Database::DateTime#subtract_datetimes

Find the first of the `end_time_attrs` that isn't `NULL`. Subtract from it
the first of the `start_time_attrs` that isn't NULL. `SELECT` the resulting interval
along with an alias specified by the `as` parameter.

Note: For MySQL, the interval is returned in seconds.
      For PostgreSQL, the interval is returned as an INTERVAL type.
