What is Clock.exe?

The genuine Clock.exe file is a software component of Microsoft Windows | Freeware replacements by Microsoft | Stoic Joker's Network.
"Clock.exe" has been the name of the Microsoft Windows taskbar clock utility program since Windows 3.1. A shareware T-Clock replacement utility program by a contributor named Stoic Joker was created before 2009 (version 95) and a new version 98 (T-Clock 2010), after which Stoic Joker put the source code in the public domain (late 2013) and said he had no more time for it because Microsoft appeared to be moving away from the Taskbar concept. T-Clock 2010 runs on Windows XP, Vista, and 7. Windows 8 users should avoid it unless interested in open-source development. Versions after "T-Clock 2010" (version 98) may become available as freeware or shareware but will probably be altered from Stoic Joker's version and may behave differently.
