SQLITE group by

I use the sql below in sqlite to group by time intervals. The first is group by day and the second group by hour:

select strftime('%Y-%m-%dT%00:00:00.000', date_time),line, count() from entry group by strftime('%Y-%m-%dT%00:00:00.000', date_time)

select strftime('%Y-%m-%dT%H:00:00.000', date_time),line, count() from entry group by strftime('%Y-%m-%dT%H:00:00.000', date_time)
