[postgis-users] Help with query

[Pedro Doria Meunier]

This is probably not the best place to be asking such a (lame) question but
perhaps someone is gracious enough to lend me a hand. ;-)

 

I have the following setup in a table:

 

The first record which is to be found (ok easy enough :D) with a timestamp
meets a certain condition (ignition off)

The following record is for the event of ignition on again with a timestamp.

 

So the question here is: how can I compute the time difference between these
two records in a single query?

Better yet: finding all the records that meet the first condition (ignition
off) and the immediately following records as to compute the time
difference. ;-)

 

Thanks in advance!
