12Ghosts - ShowTime


What does it do for me?

Enhance your taskbar clock to show the date and a second time zone. You may display seconds smaller and the date in a different color, for example. Everything is configurable, the display of the date and time, font, size, colors, alignment, and shadow effect.

12-ShowTime displays the time and date either in the tray or in a free movable window, which can be set to stay in the title bar of the active window. It displays the phase of moon and age of moon. A configurable tray icon can display a part of the date or time.

It wouldn't be a real clock if it didn't have an alarm that can be set daily or at a certain date. You may choose as alarm melody any .wav or .mid file. The comfortable snooze function reminds you repeatedly until it is answered. With a configurable list of 12 world times in a separate, movable window, chimes every quarter, hour signal, chronograph, and quickly accessible countdown the program is powerful and a pleasure to use.


Where should I start?

After starting 12-ShowTime the first time you should notice a new layout of your clock in the taskbar tray. (You may need to enable the tray clock with START - Settings - Taskbar - and check "Show clock".) Click in the right half of the clock to open the 12-ShowTime settings window. Right-click to open the context menu.

In the Clock settings select a date format, select a color scheme, and enable or disable 24 hour format and seconds. Reduce the size of date and seconds to increase the visibility of your clock. Insert a world time for any time zone worldwide, including local daylight saving adjustment.

In the Advanced options you may change any part of the display. First select either the Main window, the tray clock, or a line of the two-line icon. Place the cursor in the date or time field to insert date or time parameters. To change formattings select the parameters, then click a format button. Of course you may edit the format string manually, too.

You may display a set of World Times in a separate, free movable window. WorldTimes display is fully customizable, choose your own description like "Auntie Mary" or "Australia", choose different colors, select any of the 74 world wide time zones, display current daylight saving time (DST, always +1 hour), display difference to Greenwich Mean Time (GMT, aka Universal Time or Zulu) and difference to local time.

Moon Always Visible - Always display the moon in the main 12-ShowTime window.

Moon on Mouse Over - Display the moon only if the mouse hovers over the main 12-ShowTime window.

Blinking Colon - always, only if an alarm is scheduled or if the stopwatch or countdown was activated, or never.

Update moon only once a minute - The age and phase of moon can be updated either every second or only once a minute.

Transparent Background - the background color will become transparent, so the clock blends perfectly into your wallpaper or the titlebar color, respectively. If the moon is activated this is a round or crescent-shaped window. Tip: either disable 'Smooth' in Clock - Advanced - Main, or choose a background color near the color of the actual background. Note that you need to click on a visible part of the window to open the settings window. (This only works on Window 2000/XP.)

Follow Active Window - display the date and time in the title bar of the active window.

You can now set the location of the window in relation to the title bar. If there's an active window and you start to move 12-ShowTime, this sets the distance to the upper right corner of the active window. If, however, there's no active application window, like when you click on the desktop, moving 12-ShowTime sets its default position.

Lock Position - Lock position of the main 12-ShowTime window. This will prevent you from inadvertently moving the window. Note, that you can precisely move the main window with the arrow keys when it has the focus.

On Top of all Windows - Always keep the main 12-ShowTime window on top of all other windows. Screen savers, however, will cover it.

Mute All Sounds - Mute all 12-ShowTime sounds. 


Frequently Asked Questions

I tried to enable TrayClock but it does not show up. Only a small gray rectangle appears in the taskbar where the clock should be.

Please turn on the Windows clock first. Click on START - Settings - Taskbar and check the option "Show Clock". 12-ShowTime extends the original Windows clock instead of adding yet another clock.

The movable 12-ShowTime window is the only clock I want. How do I remove the windows clock from the taskbar?

Click on START - Settings - Taskbar and remove the check mark before "Show Clock".

I noticed that I can specify any file, not only sound files, to play. How can I add parameters?

Yes, you can specify any file, even a batch file (a normal text file with the extension .BAT) with full command lines. However, you might want to try 12-Timer if you need to add parameters, properties or more flexible scheduling. To use all features of 12-ShowTime, like repeated chimes, you should use .WAV or .MID files. Nonetheless, you can also call up a program or any registered file type, for example, .MP3 files.

Can I wake up with a CD track?

Yes. To start a music CD track you need to create a batch file (a normal text file with the ending .BAT), with this one line:

cdplayer /play D:

where D: is your CD-ROM's drive letter. You may edit the play list to indicate the track with which to start.

Is 12-ShowTime more exact than the Windows clock?

If you mean the delayed display of seconds in the Windows Date/Time Properties or Windows Clock.exe, yes.

- Compare both times with a metronome or a loud analog wrist watch.
- Open a command prompt and enter the command "time" shortly before the next wrap of a second, compare the milliseconds.

After comparing both you will notice that the seconds in the Date/Time Properties or Clock.exe are up to half a second late. Technically, for 12-ShowTime this wrap simply cannot happen before, but only a few of milliseconds later, or exactly on the next full second.

Where can I find out more about the moon?

Er - how much more? You'll find anything for example at google.com. Search for "astronomy". You'll find several observatories with rich explanations, the NASA site, the Java UTC atomic clock, astronomic software, NTP connectors, and a lot more.

The displayed counters are the age of moon in days and phase of moon in percent. 0d 0h 0m 0s equals New Moon. The average moon cycle varies between 29.2 and 29.9 days, so Full Moon is at about 14d 18h.


Resource Efficiency

We put quite some effort into having this varied clock be sparing with system resources. The result is an astonishing low memory usage and virtually no recognizable processor time.

First, we do not run a loop in any way, shape or form to wait for the next second to happen. Instead, 12-ShowTime activates a system timer that only fires once exactly to the full second. Otherwise, 12-ShowTime does not run as an active task!

12-ShowTime saves system resources because it does only what is absolutely required. For example, it might be necessary to update the time window or tray icon every second - but only if seconds are displayed. If you have only minutes displayed 12-ShowTime does not redraw the main window until the next full minute, etc. The tray icon is repainted only once a day if you display only the day. 12-ShowTime routinely checks if any changes are necessary and - if not - returns without wasting time.

All drawing procedures have been optimized for flexibility and for saving resources. 12-ShowTime does not include 31 icons for each day and day of week, but instead creates the icons dynamically, providing for a smaller executable and full user control.

We made sure that all changes are only calculated, of course, if visible or selected: the tray icon, moon and moon text, world times, options title bar, alarm, countdown and chimes. Even if you had all options selected and visible, 12-ShowTime needs very few CPU time. In fact, you will constantly see less than half a percent processor time - hardly even measurable.
