Run As Date is a rather uncommon but pretty useful piece of software.  It allows you to run specific programs with date and time settings of your choice. RunAsDate is basically a launcher which injects (no actual program modifications) user specified date and time settings to applications launched through it. Your system time will remain unchanged but the launched apps will believe the current date and time to be the one specified by Run As Date.

This application can help you with those ‘trial or beta period expired’ error messages – majority of such time limited installers will let you install expired trials or betas if you run them with appropriate date/time settings. This is just one use of RunAsDate and I’m sure you’ll find many other scenarios where this application will be useful.

Note: If you have AVG Anti Virus or Internet Security, you may get a Trojan horse alert when trying to use this application. This is a false positive and is not actually a virus.

Developer Description

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. More information can be found on the app homepage.
