 Copy&paste from KApplication::updateUserTimestamp():

// get current X timestamp
Window w = XCreateSimpleWindow( qt_xdisplay(), qt_xrootwin(), 0, 0, 1, 1, 0, 
0, 0 );
XSelectInput( qt_xdisplay(), w, PropertyChangeMask );
unsigned char data[ 1 ];
XChangeProperty( qt_xdisplay(), w, XA_ATOM, XA_ATOM, 8, PropModeAppend, data, 
1 );
XEvent ev;
XWindowEvent( qt_xdisplay(), w, PropertyChangeMask, &ev );
time = ev.xproperty.time;
XDestroyWindow( qt_xdisplay(), w );
