In the past i use querys like this to generate some timestamp field:
select generate_series (1, 10), generate_series('2018-01-01
10:00'::timestamp, '2018-01-02 10:00'::timestamp, '10 hours');

in some case I need to order the timestamp data field and in others I just
need an interval. So, in some moments an random data already help me and in
others it is necessary to have both fields aligned.

thanks
