Second Clock is a software that allows for the display of a secondary clock in a different time zone on your menu bar. By pressing the Command key and dragging the menu bar item, users can easily adjust its position on the menu bar. In instances where the application doesn't appear in the menu bar, this could be due to macOS concealing menu bar apps when there's no space left, a problem often encountered on MacBooks with a notch. The solution is to quit some other menu bar apps to create space. If this doesn't resolve the issue, users with Bartender installed could try quitting this application. The software offers customization options such as the ability to display a flag emoji or a Unicode character/SF Symbol in front of the time. This is achievable through the "Prefix text" setting. To utilize an SF Symbol, the SF Symbols app needs to be downloaded, a symbol copied, and then pasted into the "Prefix text" setting. However, it's important to note that the software does not have the capability to display seconds or the date. For displaying seconds, users can adjust the system clock settings.
