Hi
I use the <timestamp/> element (section 4.1.7 of RFC 3863) of <tuple/> to
detect the most recent tuple and ignore the outdated ones.
Problem, the <timestamp/> is an optional element and your clients may not
insert it when publishing. Do you control the client source code that
publishes the presence information ? If no we should find a way in openser
presence module to add this timestamp element for you. I add a quick look at
PRESENCE and PRESENCE_XML but I haven't find anything yet.
Regards,
Pascal

Guys,
while dealing with presence/presence_xml modules, I came into one situation
when one user crashes simultaneously and each time displaying different
presence info (online, away, offline). Have noticed that the presence server
is smart enough to inform all the other watchers about three different
status information for the same user.
My question is, how can the watcher know the most recent status
information. Have looked on both order of info in the tuple as well as on
ids but did not find any logic. Can u please guide me about possibilities I
have?
Thank you in advance,
DanB
PS: FYI, I am pasting such a tuple example.
<tuple xmlns="urn:ietf:params:xml:ns:pidf" id="t9062">
