Get date time in seconds under the hood

Hi everybody,

I'm working on a test bench with a PCI card Meinberg PTP270PEX.

This card is able to overwrite the Windows System time with a Windows service working transparently.

Since Windows 8, a new time management has been introduced, allowing to get timestamps with a true µs resolution. So, it's possible to get high resolution time under Window using the "GetSystemTimePreciseAsFileTime" fonction of Windows.

My question is : what does exactly the standard "Get date time in seconds" of LabVIEW Under the Hood ?

GetSystemTimePreciseAsFileTime call or a standard GetSystemTime call ?

I don't want to do a dll call from labVIEW because of the calling time of the dll which will introduced a time offset on the timestamp.

Best regards,
