In the main window of RunAsDate, select the desired date and time and the application that you want to run. In order to start using it, simply copy the executable file (RunAsDate.exe) to any folder you like, and run it.
RunAsDate doesn't require any installation process or additional DLL files. RunAsDate intercepts the kernel API calls that returns the current date and time (GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime), and replaces the current date/time with the date/time that you specify. 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. RunAsDate is a small utility that allows you to run a program in the date and time that you specify.RunAsDate will not change the current system date and time of your PC, butit only injects the date/time that you specify into the desired application.
