As Matt Johnson noted, Microsoft fixed this on December 12, 2017, and computers
that get regular updates for Microsoft Windows should be OK. I expect that users
will be out of luck if their computer is running an unauthorized version of
Microsoft Windows, or is running a version so old that Microsoft no longer
supports it. The current rules for which versions are too old is summarized in
The situation with Google is more complicated, since Google typically
distributes Android indirectly via OEMs like Samsung, Huawei, and Xiaomi. Since
each OEM traditionally has treated their platforms the way Microsoft treats
Microsoft Windows, each OEM needed to incorporate time zone changes and users
need to update their phones' system software. This procedure was streamlined in
Android 8.1 (see
<https://source.android.com/devices/tech/config/timezone-rules>) so that OEMs
can push updated time zone information without requiring a system update;
however, most Android phones run releases older than 8.1 and so must go through
the older, more-lengthy update process.
There should be a simple workaround for computers or phones that are not updated
properly: users can set their time zones to Cairo time.
