@Hardy,
The clock is displayed in Arabic digits because there is no option in my phone to select 'Marathi' as display language for whole interface.

Yes they are. But if we use that logic then the application does not need be translated to languages other than English because anyone who uses Android must be sufficiently familiar to English language already.
If this is an Android issue (which we haven't yet conclusively proved) then I will take the complaint to Android forum. Until then let's keep this topic open.
