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 normal.
- RunAsDate doesn’t require any installation process or additional DLL files. In order to start using it, simply copy the executable file (RunAsDate.exe) to any folder you like, and run it.
- In the main window of RunAsDate, select the desired date and time and the application that you want to run. Optionally, you can also specify the command-line parameters to run the program. Press the "Run" button to start the application with the specified date/time.
How does it work ?
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.
RunAsDate works under Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7. Older versions of Windows are not supported. The is also x64 version available in a separated download, for using with x64 applications.
