The Taskbar Clock in Windows displays the date and time. The day, month and the year are displayed – and the hour and minutes are seconds are displayed. In this post, we will see how to show or display second in the Taskbar Clock using the Registry in later versions of Windows 11/10, or third-party freeware on Windows 7/8.
Before we proceed, it is important to know, why Microsoft did not build this capability into the Windows operating system, to begin with. Was the constant blinking of the colon too distractive?
The blinking colon and the constantly-updating time were killing our benchmark numbers. On machines with only 4MB of memory (which was the minimum memory requirement for Windows 95), saving even 4K of memory had a perceptible impact on benchmarks. By blinking the clock every second, this prevented not only the code paths related to text rendering from ever being paged out, it also prevented the taskbar’s window procedure from being paged out, plus the memory for stacks and data, plus all the context structures related to the Explorer process. Add up all the memory that was being forced continuously present, and you had significantly more than 4K.
Now that we know why the Windows Taskbar Clock does not display seconds, let us move on.
We have already seen how to how to add the day of the week to the taskbar clock, now let us see if we can add seconds to the Taskbar Clock time.
Display seconds in Taskbar Clock
There is no way to natively display seconds in the Taskbar Clock in Windows 8 or Windows 7. However, Windows 11/10, will allow you to do so, by tweaking the registry.
If you wish to show the seconds in the Windows taskbar easily, you will have to use 3rd-party free tools like T-Clock Redux or TClockEx.
T-Clock Redux in an enhanced fork of Stoic Joker’s T-Clock 2010. Apart from letting you display the seconds too, it offers many other features. It works on Windows 8.1/7 and Windows 10 too. TClockEx is such a free tool that can help you show seconds. This one also lets you tweak additional options in the Taskbar Clock.
Users on Windows 11/10, can open Windows Registry, navigate to the following registry key
create a new REG_DWORD, name it ShowSecondsInSystemClock and give it a value of 1.
