Make your taskbar clock show seconds
The clock at the bottom right of your taskbar only displays the time in hours and minutes. If you prefer a little more precision, there’s an easy way to make it show seconds as well. Press the Windows key, type regedit, press Enter, then click Yes to open your PC’S Registry Editor.
Now navigate through the following folder path using the dropdown menus on the right: HKEY_CURRENT_USER\ Software\microsoft\windows\ Currentversion\explorer\advanced. Right-click the Advanced folder on the left, move your cursor to New in the pop-up window that appears, then select ‘DWORD (32-bit) Value’. Next, type Show second sinsys temclock, then press Enter. Now double-click this value, click 1 in the ‘Value data’ field, click OK (see screenshot below), then close the Registry Editor.
Restart your PC and your taskbar clock will now display seconds.
