Summary
Function: string llGetDate( );| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a string that is the current date in the UTC time zone in the format "YYYY-MM-DD".
If you wish to know the time as well use: llGetTimestamp which uses the format "YYYY-MM-DDThh:mm:ss.ff..fZ"
Examples
// Birthday surprise
default
{
state_entry()
{
llSetTimerEvent(0.1);
}
timer()
{
if(llGetDate() == "2009-02-15")
llSetText("HAPPY BIRTHDAY!", <0,1,0>, 1.0);
else
llSetText("A surprise is coming...", <0,1,0>, 1.0);
llSetTimerEvent(3600.0); // check every hour.
}
}
// Function to calculate the numeric day of year
integer dayOfYear(integer year, integer month, integer day)
{
return day + (month - 1) * 30 + (((month > 8) + month) / 2)
- ((1 + (((!(year % 4)) ^ (!(year % 100)) ^ (!(year % 400))) | (year <= 1582))) && (month > 2));
}
default
{
touch_end(integer count)
{
list dateComponents = llParseString2List(llGetDate(), ["-"], []);
integer year = (integer) llList2String(dateComponents, 0);
integer month = (integer) llList2String(dateComponents, 1);
integer day = (integer) llList2String(dateComponents, 2);
llSay(0, "The current day of the year is " + (string) dayOfYear(year, month, day));
}
}
// Function to calculate whether a current year is a leap year
integer is_leap_year( integer year )
{
if( year % 4 ) return FALSE; // Not a leap year under any circumstances
if( year <= 1582 ) return TRUE; // In the Julian calender before 24 February 1582, every fourth year was a leap year
if( !( year % 400 )) return TRUE; // A leap century is a leap year if divisible by 400
if( !( year % 100 )) return FALSE; // Any other century is not a leap year
return TRUE; // It is divisible by 4 and not a century and not Julian, therefore it is a leap year
}
The previous script is way unnecessary for Avatar age, SL sales history etc. Here is all that is needed for 99% of SL applications.
This code is in fact valid for all years from 1901 to 2099, as 2000 was a leap year.
if (year % 4) // TRUE if NOT a leap year
Useful Snippets
Helper Functions
- Timestamp: list format to Unix timestamp - ex: [2009, 2, 13, 3, 31, 30] to 1234567890
- compatible with llParseString2List( llGetDate(), ["-"], [] ) (reports as first second of given day)
- Timestamp: Weekday from (Y, M, D) - ex: "Friday" from (Y, M, D)
