As I understand it, it is not so much the API as the operating procedure
underneath. One problem is that when an MS-Windows machine is powered off during
a DST transition, it does not update the time properly when it is powered back
on. In a How-To Geek article published earlier today, Chris Hoffman says the
problem occurred with MS-Windows 10 this weekend, and I recall hearing about
similar issues years ago. See:
Hoffman C. Some Windows 10 Clocks Didn’t “Fall Back,” Here’s How to Fix It.

Kuhn M. IBM PC Real Time Clock should run in UT. 2016-10-29.
PS. I don't know whether the "EDT" in Hoffman's article's timestamp reflects the
MS-Windows 10 bug or is a subtle joke; it could be both.
