Change the display of the clock in the taskbar

The clock in the taskbar can be changed to show not only the time, but also the date, or just the date, or nothing at all.
To show nothing:

 HKLM\Software\Microsoft\Shell\TBOpt = 0 (DWORD decimal)

To show just the clock:

 HKLM\Software\Microsoft\Shell\TBOpt = 1 (DWORD decimal)

To show just the date:

 HKLM\Software\Microsoft\Shell\TBOpt = 2 (DWORD decimal)

To show both the date and the clock:

 HKLM\Software\Microsoft\Shell\TBOpt = 3 (DWORD decimal)

Note 1: If you switch to the Analog clock display, the date will remain visible -through- the Analog clock
Note 2: Setting the clock to show 'nothing' will still keep the reserved space, showing the taskbar background, and obscure any icons that will shift to the right.
Note 3: Your date may get obscured by the space reserved for the OK/Close button in the top-right. You can fix this my adding spaces at the end of your 'Short Date Format'. See also the tweak on 'Change the Short Date Format'

Hide/Show battery indicator in Task bar

If you wish to hide the battery indicator in the task bar on some devices, you can set:

 HKLM\Services\Power\ShowIcon = 0 (DWORD decimal)

And to show:

 HKLM\Services\Power\ShowIcon = 1 (DWORD decimal)

Note that this icon and its feature may not be available on your device at all. For example, the HTC Wizard regularly ships with a battery indicator in the Tray instead, governed by "Windows\Startup\InitTray.exe".
Note also that this reportedly does not work on AKU2 ROMs to remove the new battery indicator

Show the clock in all applications

This tweak can be set through: Start > Settings > |System| > Clock & Alarms* > |More| > [x] Display the clock on the title bar in all programs To show the clock on the titlebar in all applications:

HKLM\Software\Microsoft\Shell\TaskBar\LimitedClock = 0 (DWORD decimal)

To hide it again (only visible on Today Screen):

HKLM\Software\Microsoft\Shell\TaskBar\LimitedClock = 1 (DWORD decimal)

Restore Clock on Taskbar when on Today Screen

The AKU2 update brought with them a, arguably lame, battery icon which replaced the Clock. Although the clock can be restored when running applications, it is permanently removed when on the Today Screen. Microsoft have addressed users' concern over this in the AKU2.2 update. You can restore the clock entire by setting the following:

 HKLM\Software\Microsoft\Shell\ShowTitleBarClock = 1 (DWORD decimal)
