This does not explicitly address the original question that prompted
the text.  It appears that the common parlance in several equatorial
east African regions is to have hour 0 and the change of date at 06:00
according to cell phones that are showing UTC+3.  Therefore people who
wish their devices to give common time (and date) rather than cell
phone time (and date) have already been and can continue to be able to
achieve this by setting a device to use UTC-3.  The flaw in this
scheme is that device vendors may not have allowed that as one of the
choices.

Is there objection to enhancing the patch text to mention this explicitly?
