That function is very nice, Westie. I may use it in the future.

I'll post a function that calculate time with an offset:

Код:

stock ShiftTime(&y=0,&mo=1,&d=1,&h=0,&m=0,&s=0,sy=0,smo=0,sd=0,sh=0,sm=0,ss=0){
	new days[12]={31,28,31,30,31,30,31,31,30,31,30,31};
	s+=ss;
	m+=sm+(s/60);
	h+=sh+(m/60);
	d+=-1+sd+(h/24);
	mo+=smo-1;y+=sy+mo/12;mo%=12;
	if((!(y%4)&&(y%100))||!(y%400))days[1]=29;
	for(new i=sign(d);d/days[mo];d-=i*days[mo]){
		mo+=i;
		if(mo>11||mo<0){
			y+=i;if((!(y%4)&&(y%100))||!(y%400))days[1]=29;else days[1]=28;
		}mo%=12;
	}s%=60;m%=60;h%=24;mo+=1;d+=1;
}stock sign({Float,_}:x){if(x>0)return 1;else if(x<0)return -1;return 0;}

First 6 values are simply integers to get time from. You can put them variables with stored date and time. The other are offset for the time (sy: year offset, smo: month offset, sd: day offset, sh: hour offset, ...)
Offset values can be any integer values including negative values.
That's all.
