DST TIme

[maste98]

Is the dst functionality accurate? For example I live in America central time, we are currently in daylight savings, but when calculating salah times I have to put dst as 0, because if I put it as 1 it will be an hour ahead and inaccurate . Similarly when daylight savings turns off, I have to change the dst value to -1. I can still use it like this, but it seems as though the dst integer is off by 1, 0 should mean off(no dst), 1 should mean 1 hour of dst, etc.

hello for calculate Automatic i use this method. val location = Location(latitude, longitude, altitude, GMT_DEFF, DTS)

For DTS Automatic

   public int GMT_DSTSavings(){

        Calendar c = Calendar.getInstance();

        TimeZone z = c.getTimeZone();
        int offset = 0;
        if(z.inDaylightTime(new Date())){
            offset = z.getDSTSavings();
        }
        return offset / 1000 / 60 / 60;
    }

For GMT_DEFF Automatic

    public double GMT_Decimal(){

        Calendar c = Calendar.getInstance();

        int offsetHrs = offset / 1000 / 60 / 60;
        int offsetMins = offset / 1000 / 60 % 60;

        return Time_to_Decimal(offsetHrs,offsetMins,0);
    }

//Convert Time TO Decimal Double

    public double Time_to_Decimal(int hours , int minutes , int seconds){
        return  hours + (minutes * 0.016666666666667) + (seconds * 0.000277777777778);
    }
