Kindle Touch doesn't respect LC_TIME?

[silverzhao]

My Kindle Touch is 5.3.2.1. I want to set its clock format from 12- to 24-hour format.

From the wiki here I know to change LANG=en_GB.utf8 may do this work.

But AFAIK, it is LC_TIME that controls what format date should use. So I change /var/local/system/locale like this:

LANG=en_US.utf8
LC_TIME=en_GB.utf8
LC_ALL=

then I restart Kindle. However, it doesn't work. It still shows like 1:00 PM. But I"m sure that LC_TIME has been changed to en_GB.utf8 through

# locale

So what's wrong here? How could I change the clock format but not language setting? Thank you!

You could go to the settings menu and change the language from en-US to en-GB

Time formatting in title bar is handled completely by JavaScript code at /usr/share/webkit-.0/pillow/javascripts/default_status_bar.js. It relies on (non-standard?) DateTimeFormat object accessible from JavaScript and provided by Kindle's WebKitGTK library. Object constructor has following signature:

/**
 * Creates an instance of DateTimeFormat object.
 *
 * @constructor
 *
 * @param {string} format Datetime format (at least, "short-time" is recognized).
 * @param {string=} timeZone Optional time zone for converting current time (at least, "GMT" is recognized).
 */
function DateTimeFormat(format, timeZone) { /* ... */ }

Formatting code uses format method of this object, which expects standard JavaScript Date object as parameter.

I believe, DateTimeFormat object forwards formatting requests to ICU library object created by DateFormat::createDateTimeInstance function.

It's possible to change time format independently of current locale with runtime replacing of DateTimeFormat object by executing following command:

lipc-set-prop com.lab126.pillow interrogatePillow '{"pillowId": "default_status_bar", "function": "DateTimeFormatter = {\"format\": function(date){return date.getHours()+\":\"+date.getMinutes();}}; StatusBar.clock.update();"}'

(It will change time format to 24-hour and will work only until Pillow restart or full reboot).

Thank you! It's very helpful! I'll have a try.
