* $Log: clocks.c,v $
* Revision 1.12 2005/08/02 21:14:22 courtc
* added more i18n
*
* Revision 1.11 2005/06/20 13:48:01 yorgle
* Cleaned up event stuff to use the new #defines
*
* Revision 1.10 2005/05/31 16:02:22 yorgle
* Cleaned up some colors. Why didn't anyone tell me this looked like crap? ;)
*
* Revision 1.9 2005/05/30 02:00:33 yorgle
* Clockzilla strikes again!
* Added another face (a "watch" face, based on the "OVERSIZED" face), which displays the day of week and day of month, much like many watches do.
* Converted over the vector text display to use strftime() instead of a char[][].
* removed the months[] array.
* This should work better for non-english based systems, I hope.
*
* Revision 1.8 2005/05/26 05:30:30 yorgle
* Sproing tweaks. Hopefully, sproingy hands should look a little better on 'photo
* The table may need to be tweaked.
*
* Revision 1.7 2005/05/26 04:27:00 yorgle
* Timezone arrays moved into clocks.c from menu.c
* DST arrays added
* World clock complete and hooked in. (ipodlinux.org/WorldClock for info)
* Added WORLD DST into the settings array
* Re-ordered the time-based settings items
*
*
* 2005-05-25 - switched to cvs log above...
*
* 2005-05-24 - Sproingy seconds hand for analog clocks
*
* 2005-05-08 - Added TIME_TICKER, TIME_1224 settings
*
* 2005-05-01 - Cleaned up Digital clock look (for monochrome ipods)
* Oversized clock added
*
* 2005-04-27 - Analog clock visual enhancements
* Binary clock bugfix (0..23 doesn't fit in 4 bits)
*
* 2005-04-26 - Time and Date setting added (Scott Lawrence)
* it's not perfect, but it's good enough for now.
*
* 2005-04-17 - Binary clock face added (Scott Lawrence)
*
* 2005-04-16 - BCD clock face added (Scott Lawrence)
*
* 2005-04-15 - integration (Scott Lawrence)
* - added hold switch sensing for full-screen view
* - added in my old vectorfont clock (2005-02)
* - action button toggles face style
*
* 2005-04-13 - initial Analog version (Scott Lawrence)
* - basic version done.
* - deco, normal look
* - ready for time adjustment code (get/set time)
* - (update changed from 16ms to 1000ms)
* - (courtc's titlebar update fix)
