Date difference to run something

Hi masters!

I m searching a script to do this:

(1)- When the object is rezzed he "read" the actual date.

(2)- First he check if the date is between a pre-programable date like 11/19/2007 to 11/25/2007 - one week;

(3)- If the object is rezzed on the programable interval then he run. If not , the script kill the object via llDie or kill something important like a script.

I start my research here: http://www.lslwiki.net/lslwiki/wakka.php?wakka=time, then here: http://www.lslwiki.net/lslwiki/wakka.php?wakka=LibraryTimestampDifference

I m trying but to me is very hard manipulate dates and time routines.

Any master can help me?

If you have to use a fixed window of time, then you can do this:

on_rez:
CurrentTime = llGetUnixTime();
if ((CurrentTime < StartTime) || (CurrentTime > EndTime)) {
llOwnerSay("Not within allowed time window. Deleting self!";
llDie();
}

Then you just set the StartTime and EndTime to the corresponding Unix timestamps (they are integers) for the exact times you want the object to run within. There are a bunch of websites out there which convert real date/time values to Unix timestamps and back again.

If you are just wanting to make like a demo product, which starts when the object is first rezzed, then you can do something like:

on_rez:
CurrentTime = llGetUnixTime();
if (Started) {
if (CurrentTime > ExpireTime) {
llOwnerSay("Time expired. Deleting self!";
llDie();
}
} else {
ExpireTime = CurrentTime + ActiveDuration;
Started = TRUE;
}

Started starts off FALSE. ActiveDuration is set to the length of time the object is allowed to work, in seconds. So, if you wanted the object to work for exactly one week, set ActiveDuration to 60 * 60 * 24 * 7.

If the object needs to check while it is rezzed, then you can stick the same check in the timer() event and use llSetTimerEvent(60.0) to check every minute.

Bingo Talarus. Thank you very much. Really is for a demo product.

beware, that if the user rezzes the object on no script land, they can delete the scripts from the object, even if the object is no-mod.... (it shouts that you can't modify the object, but still deletes/moves the script to inventory)

this is ok if the script is what makes the object work, but very bad if it's the object itself that's the selling point
