RunAsDate 是一個用來破解有時間限制軟體的小工具，該軟體的使用那是相當的簡單，甚至還可以建立運行在特定日期時間的快捷方式，方便以後的使用。
RunAsDate is a small utility that allows you to run a program in the date and time that you specify. This utility doesn't change the current system date and time of your computer, but it only injects the date/time that you specify into the desired application.
You can run multiple applications simultaneously, each application works with different date and time, while the real date/time of your system continues to run normally.
