Summary

Function: float llGetWallclock( );

Returns a float that is the time in seconds since midnight Pacific time (PST/PDT), truncated to whole seconds. That is the same as the time of day in SLT expressed as seconds.

For GMT use llGetGMTclock

Examples

// Real World Sun
integer Flag;

default
{
    state_entry()
    {
        Flag = -1;
        llSetTimerEvent(0.1);
    }
    
    timer()
    {
        float time = llGetWallclock();
        if (Flag == -1)
        {
            llSetTimerEvent(60.0);
        }
        if (time < 21600)
        {
            if (Flag)
            {
                llSetText("The Sun is coming! :)", <1,1,0>, 1.0);
                Flag = 0;
            }
        }
        else if (time < 64800)
        {
            if (Flag != 1)
            {
                llSetText("Sun has risen. :(", <1,0,0>, 1.0);
                Flag = 1;
            }
        }
        else if (Flag != 2)
        {
            llSetText("Goodbye Sun. :(", <1,0,0>, 1.0);
            Flag = 2;
        }
    }
}

// Convert to human-readable HH:MM:SS format
string ConvertWallclockToTime()
{
    integer now = (integer)llGetWallclock();
    integer seconds = now % 60;
    integer minutes = (now / 60) % 60;
    integer hours = now / 3600;
    return llGetSubString("0" + (string)hours, -2, -1) + ":" 
        + llGetSubString("0" + (string)minutes, -2, -1) + ":" 
        + llGetSubString("0" + (string)seconds, -2, -1);
}

default
{
    touch_start(integer total_number)
    {
        llSay(0, ConvertWallclockToTime());
    }
}

Notes

To determine if the current time returned by this function is PST or PDT, you can look at the difference between llGetGMTclock() and llGetWallclock(). The difference will be either 8 hours or -16 hours for PST, and 7 hours or -17 hours for PDT, that is 28800 or -57600, or 25200 or -61200 seconds.
