Description
IMPORTANT NOTE: This tool has not been updated to work with SU3, and it's uncertain whether I'll be able to figure out how to make it compatible.
This utility offers a workaround to the MSFS 2024 bug / behavior where the in-sim clock stays locked to real-time / system time or a fixed offset, even if you pause or use sim rate acceleration. This is unlike MSFS 2020, where pausing would pause the in-sim time, and using sim rate would accelerate / decelerate the progression of in-sim time accordingly.
It also offers the ability to select an app which will be automatically killed when sim rate is more than 1x, and restarted when it drops back to at most 1x (e.g. RealTurb, or other sim-rate sensitive apps).
This utility only adjusts an internal variable of MSFS 2024 which is the "seconds offset off of system time", and won't resolve other side-effects of that behavior / bug, like the incorrect fuel usage of first-party aircraft, where present. Not by design, anyway!
Like MSFS_AutoFPS, this utility does its work using undocumented methods through runtime memory editing. My attempts to resolve this bug using the native SimConnect variables and events was fruitless, as those appear to be all broken as of the time of writing. You can read more here.
Hopefully Asobo / Microsoft will just fix this bug / behavior and make it work like MSFS 2020, and this utility will no longer be necessary, just like my Airport Override Checker for MSFS 2024 utility. Fingers crossed!

The Airport Override Checker for MSFS 2024 is a utility that helps users manage modded airports in their Community folder by ensuring appropriate overrides for Asobo/Microsoft Streamed Packages. It scans both the Community and Streamed Packages, suggesting and automatically creating overrides as needed. While recent updates to MSFS 2024 allow for managing these packages through the in-game Content Manager, this tool remains available as an alternative for users who prefer it.

So unfortunately, I can't promise that this tool will be updated to be SU3 and later compatible, but I'll keep thinking on whether there's some approach to figuring this out that I'm missing.
Sorry to be the bearer of bad news.

This requires you to be currently using real time in-sim, otherwise this method will fail.
