Clock latest version is

Main feature overview

Clock is the upper most program always showing you the current time and date of more than 3 self selected cities in selectable time zones. Clock is thus ideal for companies having multiple offices in different time-zones as the Windows 10 clock is limited to only three clocks. Clock can be made invisible by hovering the mouse over Clock. This also allows for clicking-trough, so the applications beneath Clock can be accessed without moving or minimizing Clock. Clock is free.

Read the features in detail here.



The first version of Clock was a 16 bit Windows 98 and 2000 version written in Visual Basic. Upon noticing that Clock launched an entire 16 bit environment (WOW) on Windows XP machines, it was time to redesign the Clock application using 32 bit Turbo Delphi. Now we have entered the 64 bit arena with Windows 7, 8 or 10. Again Microsoft came up with a 32 bit environment, called (WOW64), and loads it for 32 bit applications. So it was time to rewrite Clock with Visual Studio C# so it can fully use the 64 bit .net platform.


The program Clock is designed as a very easy program, packed with features:
  • Easy readable 24 hour Clock and date per city
  • Add custom cities and select the time zone
  • Browse-buttons to browse through the selected cities
  • Selectable date format
  • Customizable background and font colors
  • No installer required
  • Settings retained per user
  • Automatic Daylight Savings Time (DST) switching upon the selected time zone
  • Daylight Saving Time indicator can be turned on or off
  • Reorder the cities as preferred by the end user
  • Right click popup menu to configure Clock
  • Clock has no icon on the taskbar, saving you screen real estate
  • Clock is very resource friendly while running and on disk
  • Completely manageable for network administrators using the registry or GPO
  • Version checker. Once a month the program checks for updates (Can be turned off by network administrators)
  • The location of Clock is remembered.
  • Clock is free.


The program Clock is licensed according to the EULA in the download. Read the EULA carefully before using the program. A recent copy can be downloaded here

Download, unzip and copy the program Clock anywhere you want on the disk.
Should you want the program to start automatically, just copy it to :

First Run

When the program Clock starts for the first time, a window (see image) is shown asking for the current place. A default time zone will be presented if it can be detected from the current Windows settings. Otherwise the user can select a time zone. This window needs to be filled in for the program to function correctly.

How To

  • Preset places/cities and time zones.

    A network administrator can predefine multiple corporate places/cities and accompanying time zones for Clock by loading the values from a Windows registry file or Group Policy Object (GPO). The default registry location is:
    The actual registry Value name is "Clocks" of the type REG_MULTI_SZ.
  • Set Date format

    Currently Clock supports the two most used date formats:
    • Day - Month - Year (dd-MM-yyyy)
    • Year - Month - Day (yyyy-MM-dd)
    This can be predefined by network administrators by setting the registry Value "DateFormat"
  • Show Daylight Savings Time (DST) indication

    A network administrator can set the DST indicator, by setting the Registry Value "ShowDST" to the string "False" or "True". The end user can overrule this by using the "Select Date Format" window.
  • Update check

    Default Clock will check once a month for updates. Network administrators can block the automatic update check by setting the Registry Value "BlockUpdateCheck" to "True". The end user can request an update check using the About box.
  • Colors

    The text and background colors of Clock can be preset by setting the registry values "TextColor" and "BackColor". This enables customization by enforcing corporate house style colors. The program must not be running to change colors and (visual impaired) users can overrule the setting by right clicking and selecting a new Text and Background color or reset to the default blue scheme (BackColor=Aqua and TextColor=Blue). Colors can be specified as HTML compatible color names "Blue, Black, Red, etc." or more precise HTML Hexadecimal codes "0x0000ff, 0xff00ff, etc."
