Convertng FILETIME timestamp to QDateTime and back again

[grabnerj]

I need to convert a FILETIME timestamp to QDateTime and back again. The data I receive and send uses a FILETIME structure to pass the UTC date and time around. I need to do this without lose.

I need to do this without lose.

QTime has 1 ms accuracy (on some systems it might be worse), while FILETIME has 100 ns. You can't do that without a lose.

is it possible to so it at 1ms accuracy?

You can use FileTimeToSystemTime() and pass appropriate fields to QTime constructor.
