If you need to tell a program to run at a specific time or date without changing your system time/date settings, RunAsDate is the freeware utility you're looking for. It's a simple portable utility that can set specific time and date settings into only the programs or applications that you select. Unlike other similar tools, RunAsDate does not affect the system time and date settings, and you can run multiple different programs and apps simultaneously with their own date and time parameters.

If your kernel API calls a date/time return, it will intercept it and replace it with what you want. You can use RunAsDate to do this by intercepting it on the phone and replacing them.

Phone calls with this API are: These calls are intercepted on. GetSystemTime, GetLocalTime, GetSystemTimeAsFileTime, NtQuerySystemTime, GetSystemTimePreciseAsFileTime.

Does Not Change System Time and Date Settings

RunAsDate is an intuitive program that has a simple user interface. To successfully use this program, there is no need to know how to program or code. Input parameters:

...>date_ofday/movetime/dd*mm*yyyy: hh.mm:ss} [Program to run] {Program parameters}

Another keen feature of RunAsDate is the ability to create desktop shortcuts for specific configurations, allowing you to launch them again and again.

A simple tool for debugging RunAsDate allows you to determine whether an application is still retrieving its time or date based on its server settings (instead of its settings on the server) or if a local time difference, daylight savings issue, and even leap years are not functioning properly.

You can access RunAsDate in English here. Utilities for Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, Windows 7, Windows 8, and Windows 10 are compatible. Other older versions of Windows are not supported, but there is a 64-bit version available for use in specific x64 applications only.

Likes the nirsoft API interface associated with RunAsDate. I am a programmer by trade; however, I like the idea of controlling schedules using graphical languages. Since I can combine the two options on this menu, I don't feel like I'm losing control over my system anymore. Apps that display graphic content should take note of the small size as an effort to make them more aware of their limits.
