Clock Doctor

Why does your clock call the azan at the wrong time?

Type the times your clock shows: the Clock Doctor compares them with the correct times for your city, then tells you the cause and how to fix it on your model.

Why can a correct clock differ from the mosque by 1–3 minutes?

Precaution minutes: some authorities add a few safety minutes to the astronomical time — an administrative choice, not an astronomical one.
Rounding: clocks and timetables show whole minutes, so two correct sources can differ by one minute.
The point of measurement in the city: in a large city, the times at its eastern and western edges differ by a minute or two.
The local authority: the timetable of your country's ministry or of your mosque is the reference where you live.
