Windows API to trigger the time synchronization

Question

Is there a windows API that would achieve the equivalent of clicking the \"Update now\" button in the \"Date and time properties\"/\"Internet time\" tab (opened by double clicki

Answer 1

There is no API exposed by the time service, but to trigger a time synchronization you can use the w32tm command line tool.

In C/C++ you can do something like this:

include 

...

system("w32tm /resync /nowait");

Take a look at w32tm documentation for further options.
