Hi, I'm Paul, but you can also call me Todd and I won't get upset.

Timezones

Paul.Todd | 31 July, 2006 15:44

My rant of the week!

Does anyone else have a problem with the Clock application and Timezones on Nokia 3rd Edition devices?

Problem 1:  Times are quoted relative to GMT with daylight saving.
-------------------------------------------------------------------------------------------
For most users I think this would present a problem as for example:
The company I work for has office in Idaho, USA. This means that the time difference is normally -7 hours with respect to the UK
It is always -7 except for two weeks in the year where the daylight savings changover occurs on different weeks.

If you look in the clock timezone this reports -6 hours because it is currently in Mountain Daylight Time and not Mountain Time.
This is really confusing as the first time a user looks at it they need to realize that unlike Windows the time is adjusted for daylight saving relative to GMT.

This is more annoying in that I had to stop and think why it would be -6 hours and not -7 which it is in real life.


Problem 2: Timezones are wrong.
----------------------------------------------
The Hawaii timezone is still wrong and despite a thread in the newsgroups there is still no word from Nokia about how to apply a patch or provide an update to correct this.

Currently we have to patch the code to get this to work correctly.

Hopefully Nokia will correct this. I say Nokia, because on the UIQ 3 devices this seems to have been fixed and reports the time correctly.

Does anyone have a comprehensive list of timezone bugs they would like to add to the list?

Microsoft CE Emulator Goes Open Source

Paul.Todd | 20 July, 2006 11:28

Microsoft are definalty leading the way with their Windows CE Emulation (or to be correct Simulation).

Features include
  • CPU emulator that executes the ARM instruction set by JIT-compiling to x86
  • An MMU emulator to support virtual memory and page protection
  • A motherboard emulator that contains emulated RAM and NOR flash memory
  • A collection of peripheral devices attached to the motherboard: serial ports, LCD controller, touchscreen, keyboard, interrupt controller, programmable timers, real-time-clock, network cards, audio, etc.
  • A “DMA” interface which allows a Win32 application running outside the emulator to communicate with a WinCE application running inside the emulator, using a simple socket-like programming model.
Even though this is in effect a techview release of the emulator, it would be really nice to see Symbian provide the same level of emulation that Microsoft do, especially regarding the native arm support which provides full ARM emulation including alignment faults, which are the bane of every project that has one hacker on it :)

Come on Symbian, give us a better emulator! If Microsoft can do it and make it open source, this definitely raises the bar for you guys!

p.s FileMan is stuck in Symbian signed :(

Only one new note today, Symbian have released a new tech paper documenting the sisx file

The file browser is coming along nicely with some positive feedback!
