Assume that you develop an application by using the SystemTimeToTzSpecificLocalTime function. The application converts Coordinated Universal Time (UTC) to the specified time zone’s corresponding local time. However, when you run the application on some Microsoft Windows operating systems, the application’s performance is very poor.

Coordinated Universal Time: A high-precision atomic time standard that has uniform seconds defined by International Atomic Time (TAI), with leap seconds announced at irregular intervals to compensate for the earth’s slowing rotation and other discrepancies.
