RunAsDate for Windows

Overview

RunAsDate is a small Windows utility that lets you launch programs while pretending the system clock shows a different date and time. It’s useful when you need to observe how software behaves under alternate time settings or when an application depends on a particular date/time to function. The interface is simple: choose the program executable, specify the date and time you want the application to see, and run it.

Key capabilities

• Simulate an arbitrary date and time for any executable without changing the PC’s global clock.
• Lightweight and free to use, with a minimal learning curve for quick setup.
• Useful for examining time-sensitive features, such as license expirations or scheduled events.
• Simple file selection and parameter entry for setting the target timestamp.

Who benefits

• Testers and developers validating behavior around daylight saving, trial expiries, or scheduled tasks.
• Support engineers recreating customer issues tied to specific dates.
• Power users who need short-term date/time overrides for legacy software that checks the system clock.

How it works

1. Pick the program you want to run.
2. Enter the desired date and time values the application should see.
3. Launch the application through RunAsDate; it intercepts time queries so the app believes it is running at the specified moment.
