Current Time via Timevar2

[godofwarares]

How do I take timevar2 and manipulate it to make it display the current time?

I know this can be done, I've seen it done :o

timevar2 is the number of seconds since 1/1/1970

I know that, I didn't need a definition >_>

But I guess i'll experiment.

Do the math x-x

There are two scripts on Graal.net you might want to look at:

I have something that does this well, but is really 'barebone' right now. Once I document it and add some higher level functions, then I'll post it in the code gallery.

If you can't wait, you can also look at various time.c source files and check out the function 'gmtime'.

I requested a date() and now() function. Don't think anything will happen though .

It probably won't be too tough to write this soon, once a version with timevar3 is released (so it can be on both server- and clientside).

Ok, this is very barebone, but maybe you can make use of it. All of the hard math stuff has been done already.

PHP Code:

enum {
  SEC,   //Seconds
  MIN,   //Minutes
  HOUR,  //Hours
  WDAY,  //Day of the week (0:Sunday to 6:Saturday)
  YEAR,  //Year
  YDAY,  //Day of the year (starts at 0)
  MON,   //Month (0:January to 11:December)
  MDAY   //Day of the Month
}
const EPOCH_YR = 1970;          //Epoch Year
const SECS_DAY = 24 * 60 * 60;  //Seconds in a day

/**
  gmtime():
    Returns array (see enum)
 */
function gmtime(tvar) {
  temp.result;
  temp.dayclock, temp.dayno;
  temp.year;
  
  result = new[8];
  year = EPOCH_YR;
  dayclock = tvar % SECS_DAY;
  dayno = tvar / SECS_DAY;

  result[SEC] = dayclock % 60;
  result[MIN] = (dayclock % 3600) / 60;
  result[HOUR] = dayclock / 3600;
  result[WDAY] = (dayno + 4) % 7;  //Epoch starts on a Thurs.
  
  while (dayno >= YEARSIZE(year)) {
    dayno -= YEARSIZE(year);
    year++;
  }
  
  result[YEAR] = year;
  result[YDAY] = dayno;
  result[MON] = 0;
  while (dayno >= this._ytab[LEAPYEAR(year)][result[MON]]) {
    dayno -= this._ytab[LEAPYEAR(year)][result[MON]];
    result[MON]++;
  }
  result[MDAY] = dayno + 1;
  
  return result;
}

function LEAPYEAR(year) {
  return (!((year) % 4) && (((year) % 100) || !((year) % 400)));
}

function YEARSIZE(year) {
  return (LEAPYEAR(year) ? 366 : 365)
} 


Here is code that initializes some pseudo-const arrays and a little bit of sample code that will make use of the array that gmtime returns:

PHP Code:

//Pseudo-constarrays
function constArrays() {
  //I WANT CONST ARRAYS!
  this._ytab = {
    {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31},
    {31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}
  };
  this._days = {
    "Sunday", "Monday", "Tuesday", "Wednesday",
    "Thursday", "Friday", "Saturday"
  };
  this._months = {
    "January", "February", "March",
    "April", "May", "June",
    "July", "August", "September",
    "October", "November", "December"
  };
  //STILL WANT CONST ARRAYS!
}
function onCreated() {
  constArrays();

  //Sample Code
  temp.result;
  result = gmtime(timevar2 - 60*60*8);  //GMT - 8
  printf("Time (Pacific): %d:%d:%d", result[HOUR], result[MIN], result[SEC]);
  printf("Date (Pacific): %s, %s %d, %d", this._days[result[WDAY]], this._months[result[MON]], result[MDAY], result[YEAR]);
} 


Again, this is just all the math stuff done for you. If I get around to making functions that will return a date/time based on a format string (like PHP's time() function), I will release it in the code gallery, but maybe this can get you started with whatever you need to do.

Cool :o

I should probably mention that the gmtime() function takes a single parameter, which is the timestamp that you want converted from 'epoch time' to 'real time'.
It returns an array, and the indexes correspond with the enum defined at the beginning of the script.

Hmmm
We could add a date() function which is similar to format,
e.g. date("%Y-%m-%d",timevar2[,timezone]) which would print the time variable in a readable format. That would work on serverside-only though, the clientside timevar2 is not synchronized to the correct unix time yet (there is timevar3 on Graal3D though).

Yeah, that what I've been planning to do, but it would be better if it were built-in.

How far is timevar2 off? Only by a couple of seconds at most, it seems.

[zokemon]

timevar2 on the client is your computer's time if I recall correctly.

[godofwarares]

I'm wondering why timevar3 hasn't been released yet?
