Best Method To Find Out If Its 12AM

[queenkhaleesi]

Hi guys, what is the best way to check if its 12AM (Not the SL time), since I'm thinking of a using timer to check the date if date change from the current date then I will send the data from the past 24 hours. I know there's a best way to do it. Thanks!

There are many ways to do it. Take a look at Void's example in the LSL wiki at llGetGMTclock for a start.

Edit:  Sheesh!  I can't even type a simple sentence without typos.

Hmm I see llGetGMTclock returns seconds since midnight (12AM)? But this one uses the Inworld time right?

 

[Rolig Loon]

No.  llGetGMTclock is telling you Greenwich Mean Time and Void's example is giving you a conversion from seconds to hours and minutes, offset to your local time zone.  It's exactly what you asked for.

I see, I guess I need to educate myself about timzone like GMT, PST, etc. :matte-motes-big-grin:

Use wall clock found here:

http://wiki.secondlife.com/wiki/LlGetWallclock

 

Quick sample:

// Convert to human-readable HH:MM:SS format
string ConvertWallclockToTime()
{
    integer now = (integer)llGetWallclock();
    integer timezone = - 16; //GMT (Takes 16 hours from current time)
    integer seconds = now % 60; //seconds
    integer minutes = (now / 60) % 60; //Minutes
    integer hours = now / 3600; //Hours
    integer hourswtimezone = hours + timezone; //takes timezone from current hours
    return llGetSubString("0" + (string)hourswtimezone, -2, -1) + ":"
        + llGetSubString("0" + (string)minutes, -2, -1) + ":"
        + llGetSubString("0" + (string)seconds, -2, -1);
}
 
default
{
    touch_start(integer total_number)
    {
        llSay(0, ConvertWallclockToTime());
    }
}

I made this quick so there may be errors but should give you an idea.

 

You would want ot convert this to a loop on rez and look to see if the hours equal 12 (or 00:00)

Oh this is cool by modifying slightly the snippet. Thanks

Can't sleep so here...

string is12() //STRING COMMAND NAME
{
    integer now = (integer)llGetWallclock(); //SETS NOW AS CURRENT TIME
    integer hours = now / 3600; //TURNS HOURS IN TO 24H FORMAT
    string es = llGetSubString("0" + (string)hours, -2, -1); //ADDS 0 IF ONE DIG
    return llDeleteSubString(es, -3, -3); //REMOVES - IF HOURS IN NEG (GOOD IF MAKING TIME ZONE)
}

default //MAIN SCRIPT
{
    state_entry() //FIRST STARTS
    {
        llSetTimerEvent(60); // Activate the timer every 60 seconds (DONT WANT ANY QUICKER OR MAY ACTIVATE TWICE)
    }
    
     timer() //LOOPS EVREY 60 SECONDS
     {
         if (is12() == "00") //IS CURRENT HOUR 12 AM
         {
         //ADD THING TO ACTIVATE AT 12AM HERE:
         llSay(0,"Another Day!"); //SAY ON PUBLIC CHAT THAT ITS A NEW DAY
         }
    }
    
    
    touch_start(integer total_number) // ON TOUCH
    {
        llSay(0,"The Current Hour is " + is12() + "."); //TELL TIME (GOOD TO SEE IF WORKING)
    }
    
}

12AM being midnight, the most simple test is to test when the day changes from one date to another using llGetDate()

string dayLast;float checkRate = 60.0;default{    state_entry()    {        dayLast = llGetSubString( llGetDate(), -2, -1);        llSetTimerEvent( checkRate);    }    timer()    {        string dayNow = llGetSubString( llGetDate(), -2, -1);        if ( dayNow != dayLast )        {            // past midnight            llOwnerSay( "The new day is: "+dayNow);        }        dayLast = dayNow;        llOwnerSay( "Day is: "+dayNow); // for testing    }}

This of course is 12AM in the UTC time zone
Anyway it happens one time every 24 hours no matter what time zone you are in

Unsure why you're concerned with it activating twice when the code you have there goes off 60 times the first hour of each day.

 

// Does not account for daylight savings time changes through the year.

default{ state_entry() { llSetTimerEvent(86400 - llGetWallclock()); // set timer for midnight SLT } timer() { llSetTimerEvent(86400); // set timer for 24 hours later //ADD THING TO ACTIVATE AT 12AM HERE: llSay(0,"Another Day!"); //SAY ON PUBLIC CHAT THAT ITS A NEW DAY }}

Smart but bound to get screwed at SIM restart / SIM down

:smileysurprised::smileyvery-happy:

[Innula Zenovka]

How about adding:

changed(integer change)	{		if (change & CHANGED_REGION_START){			//do stuff to reset the time		}	}

 

[LepreKhaun]

Good point:

// Does not account for daylight savings time changes through the year.default{    state_entry()    {        llSetTimerEvent(86400 - llGetWallclock()); // set timer for midnight SLT    }    changed(integer change)    {        if (change & CHANGED_REGION_START)           llSetTimerEvent(86400 - llGetWallclock()); // set timer for midnight SLT	    }    timer()    {        llSetTimerEvent(86400); // set timer for 24 hours later        //ADD THING TO ACTIVATE AT 12AM HERE:        llSay(0,"Another Day!"); //SAY ON PUBLIC CHAT THAT ITS A NEW DAY    }}

 Anything to get away from checking every minute for a once in every 24 hour action!
