上面的问题好白痴，我找到办法了，呵呵。
不过还是挺麻烦的，如果软件有个功能是选择自己的图片，然后确定就生成带时间的墙纸多好哦……

Pre-designed Wallpaper Clock templates
The easiest way to create your own wallpaper clock is to use one of templates that I created for your convenience. Template is ready to use set of images with empty background image, so that you can add your own background, and use pre-designed hours, minutes, days and months. Here is how:
Download one of ZIP files below on this page
Unzip it into separate folder
Open "bg.psd" in Photoshop and update empty layer with design that you want
Save result as bg.jpg, then use it to create preview images: preview200x150.jpg, preview100x75.jpg
Edit clock.ini and update it with author info
Zip all files in folder again, rename ZIP file to have ".WCZ" extension (for example, myclock_800x600.wcz)
Make a copy of WCZ file and double-click it to test (you must have software that works with wallpaper clocks).
