First of all, I know that there are many questions like mine. However, I cannot understand that solutiona or they just doesn't work. So, I don't need the date and time from DEVICE. I need the real date and time in the Asia/Tashkent. Also i tried the way with
DateFormat.getDateTimeInstance():
This one shows device date and time too. In other words I need the date which user will not be able to manipulate by changing device date. At least just advice some useful APIs e.t.c. I know that there is a lot of such kind questions. Also, please, explain which part of the code is used for what.
