Prayers time and prayer time doesn't match.

[sadgirltory]

Even after having same data, settings, geo,timezone the time of prayer.time and prayers.time doesn't match.
error example:
final Prayer current = Prayer.now(settings: settings, coordinate: geo, timeZone: 6.0);
final Prayers prayers = Prayers.on(date: when, settings: settings, coordinate: geo, timeZone: 6.0);

if the current time is dhuhr the current.time shows 12:06:00.000 //the correct time
and the prayers.dhuhr shows 11:56:00.000 //incorrect time
