Wallpaper Clocks is a simple but nice application that allows you to set wallpapers that include еру date and time. The application is very simple and once you install it, it will appear on your menu bar. In order to see the wallpapers, you will first have to download the ones you like from the developer's website. There you will find lots of wallpapers with different themes and styles, and you can download as many as you like. By default, all of them will display the time and date, but you can disable this function from the Preferences menu.
The wallpaper can be displayed in the center of your screen or you can stretch it to fill the screen. The developer's website will automatically suggest which is the best resolution for your wallpaper according to your computer preferences. Sadly, you cannot set the program to change the wallpapers automatically, so you will have to do it manually from the menu bar icon, by clicking on "Change wallpaper clock".
In short, if you want to decorate your screen with beautiful wallpapers that show the time and date in a nice way, Wallpaper Clocks may be right for you.
