Hi all,<br>i have the same problem, i haven't well understood meaning and use of timestamp and duration fields.<br>From my understanding, timestamp field is start time and duration is difference between end time and start time.<br>
Is it rigth?<br>On the other hand, i know that it is a good practice don't change these 2 fields. I mean, it isn't suggested to modify duration or timestamp after that the event is inserted in session (is it right?)<br>
Furthermore, it is bad practice to insert an event with old timestamp, compared to system time.<br>So, i don't understand, how is it possible to manage event with duration.<br><br>If i have an event with timestamp t1 and duration 5s, of course i know it when it is finished, so i have to insert it into session with old timestamp.<br>
<br>Sorry for bad English, i hope i was clear.<br><br>Thanks a lot,<br><br><br><div class="gmail_quote">On Fri, Mar 9, 2012 at 5:08 PM, mind <span dir="ltr"><<a href="mailto:gil.vegliach@gmail.com">gil.vegliach@gmail.com</a>></span> wrote:<br>

events.<br>
2) Well the docs lacks information on the starting time and the ending time<br>
of events and then defines the semantics of temporal operators: there must<br>
be something missing. Moreover even looking at the example I couldn't fine<br>
anything.<br>
3) I want to set the duration though, all my software works with<br>
interval-based events...<br>
