ITL library - Wrong calculation for Asr for Malaysia

[Mansur Amir <mansuramir at pd dot jaring dot my>]

Assalamualaikum,

I just stumbled on this library. However when trying the demo app, the
calculation of the Asr prayer for Kuala Lumpur (Latitude:  3.1667,
Longitude: 101.7000) was off i.e. earlier by about 30 minutes. I was
using method 1 (Egyptian General Authority of Survey) and Shafiee way of
calculating the prayer time.

Here are the relevant amendments to the paryer-demo.c file:

/* fill the Date structure */
    date.day = 26; // (26 August 2004)
    date.month = 8;
    date.year = 2004;
    /* fill the location info. structure */
    loc.degreeLat = 3.1667; 
    loc.degreeLong = 101.7000 ;
    loc.gmtDiff = 8; // GMT+8
    loc.dst = 0;
    loc.seaLevel = 0;
    loc.pressure = 1010;
    loc.temperature= 10;

  
    /* auto fill the method structure. Have a look at prayer.h for a
     * list of supported methods */
    getMethod(1, &conf); //Egyptian General Authority of Survey
    conf.round = 0;
 
All the other times calculated are OK, just the Asr prayer. ITL calculated
as 15:58 whereas the correct time is closer to 16:30.  You can also check
using www.islamicfinder.org prayer calculator to confirm.

Can somebody check where have made the mistake? Also kprayertime using
this library also calculated it wrongly.

Wassalam.
