Lightbulb How to Correct Date/Time of Kindle (without Wireless Access)

Kindle 2 (Serial no. prefix B002) and Kindle DX (Serial no. prefix B004) was become with (U.S. Wireless).
So, anyone live outside of US and he got one of them he must register by this wireless (called: Whispernet) to obtain some options like:
  • Adjust date and time.
  • Make book collection.
  • Get options of "Settings" section.
But outside of U.S. Whispernet is uncovered in other countries.

Well, The good news there is two ways to do offline registration:

1- Nifty way:

2- Goodspeed way (Needs USBNetwork Hack):
http://mobileread.com/forums/showthread.php?t=87336

Now we have the same problem with date and time which strated from 1970 !

First step to correct it that installing the USBNetwork hack to get the shell access to Kindle OS which based on Linux.

After you get Telnet/SSH shell you can do the following steps:

Use the following syntax for date command:
Code:
date MMDDHHMMYYYY
Where MM=Month, DD=Day, HH=Hour, MM=Minute, and YY=Year.
[You can add .SS at last for seconds]

Example for date: 30-12-2011 - time: 5:15 PM ..
You must type it like this: 12 30 17 15 2010 (without spaces)
Code:
date 123017152010
To permanently store the system clock in the hardware clock just type the following command:
Code:
hwclock -w
or: hwclock --systohc

It sets the Hardware Clock to the current System Time.
PS. Hardware Clock is often called the Real Time Clock, RTC, or CMOS clock.

Here is the result by date command:
Code:
[root@kindle root]# date
Wed Nov 30 17:15 UTC 2011
Congratulations .. Your Kindle date and time has been adjasted to correct date and time.
  • To see the time (on top of screen) press "Menu" key in Home screen.
  • Type: @time in search box then hit "Enter" key or 5 ways controller to see full date and time.

- Another ways to set date and time from Linux command-line:

We should also be able to properly set the correct TZ since v2.5. I'm not on my main box, so I don't have the paths/cmds on hand, but the TZif files are somewhere in the java lib dirs, and the settings are stored somewhere in /var along other settings (ie. reginfo).

Maybe, but I don't found it, and two simple commands (date & hwclock) should be easier.

By the way, did you tried this command before ?:
/usr/sbin/updatetime

Yes, we can use date, but it's not as 'clean' as properly setting the timezone, and it may go 'squish' anytime we switch whispernet on .

Don't know about updatetime.

I think it's cleanest way :)
And if we can switch whispernet on it will be more simple way to correct date and time, but remember .. as the first line of the thread: it's about Kindle (B002 & B004) with U.S only wireless, and for other types in other places without wireless coverage.
So if wireless is working then all these steps are not needed.

Otherwise, NTP synchronization before or after manual date modification will not cause any problem as you use it on any PC with any OS.
