[tz] [IANA #985615] Sudan Time Zone change

Thu Nov 2 11:19:09 UTC 2017

Dear Eggert,

This is Mohammed Elsir from Zain, the first mobile operator in Sudan. Actually our mobile network sends the correct time zone which is GMT+2 as seen in below trace.

[cid:image015.png at 01D353DB.A197A6D0]

The thing is that some devices such as most of feature/legacy/old phones accept the sent time zone and change time correctly. But some Android device such as Samsung, Huawei, Lenovo and part of HTC reject the provided time zone and display the time zone based on lookup table inside the handset. Below is an example from Lenovo P2.

Some Handset manufactures such as apple sent messages over the internet asking for handset restart to get the new time zone. Below is an examples.

I do appreciate your kind support to contact Android handset manufactures such as Samsung, Huawei and Lenovo asking them about

1.       Why their handsets reject the network provided time zone.

2.       How can they solve this issue?

Should you need further discussion I am available on Skype @ mohammed_elsir_64 or WhatsApp @ +249912311500. Just let me know the appropriate time for you to discuss further.

Thanks in advance for your kind support.

Best Regards,

In what sense didn't they change? My Android phone's time zone menu has
entries for Cairo, Harare, and Nairobi, but not for Khartoum. If it is a
matter of the user's time zone settings, users need to change from (say)
Nairobi time to Cairo time. On the other hand, if it is a matter of the
time zone supplied from the cellular service company, then this is
something for your local cell company to address.

As I understand it, Google engineers monitor this mailing list and so
already know about the time zone change.

There is a gap between the time that Google releases software updates,
and the time that phones actually change. For example, even though I
have a Google Nexus 6P phone and live in the United States, my phone is
well behind Google's release schedule: it upgraded over-the-air to
Android 8.0 Oreo only last night, even though Oreo was released on
August 21 *. Other manufacturers' Android phones are even slower to
update. This underscores the importance of governments announcing time
zone changes well in advance: we currently recommend one years' advance
notice.

When other countries have run into similar problems, they've had some
luck by contacting the U.S. State Department and asking for its help in
adjusting the priorities of commercial providers. I suggest that you
contact the U.S. Deputy Chief of Mission in Sudan and ask for his advice
for how to proceed. See:

https://sd.usembassy.gov/our-relationship/dcm/

https://sd.usembassy.gov/embassy/khartoum/offices-departments/public-affairs/

 From what you tell me, though, the problem is likely to involve the
protocols used by your local cellular service providers (that is, the
problem may not be in Android at all), so they'll need to be in contact
with their suppliers too.
