Hi ,
I have table that represent a switch activity like this :
| date| state |
| 2005-04-20 17:00:00 | 0 |
| 2005-04-20 17:00:15 | 0 |

| 2005-04-20 17:01:00 | 1 |

If you have a row every 15 seconds, the answer is quite easy:
SELECT
A1.date
FROM
activity A1
LEFT JOIN activity A2 ON (A2.date=A1.date-'15 secs'::interval)

A1.stateA2.state OR A2.state IS NULL
ORDER BY 1
Now if you don't have a row every 15 seconds, the answer is a bit more
15 matches
