Useful Fix

One click fix incorrect time in Windows + macOS dual boot

This is one time install macOS program to fix time incorrect issue in Window + macOS dual boot system.

There is a time maintained by the system board called the RTC (real time clock). This is the clock that is maintained by the small battery present on your motherboard. Window OS expects this time to indicate local time, whereas macOS expects this time to represent UTC. For all practical purposes, GMT and UTC are the same and local times are a time relative to GMT/UTC. The RealTimeIsUniversal simply causes Windows to treat the BIOS/RTC time as UTC, just like macOS.

GMT: Greenwich Mean Time
UTC: Coordinated Universal Time

Think of UTC time as a way to represent the current time based on a standard location irrespective of local conventions (irrespective of local time, daylight savings time, etc).

IT JUST WORKS.

Run the program once on Mac then go to Windows to fix your time to Auto time zone and you’re done! After that, clocks will no longer reset and will work normally on macOS and Windows.
