Can you create a small test case showing the problem? If you've not 
changed anything, the code should still work.

4.2.7 of Xamarin.Android is really old (the alpha version is on 4.8.0 
with the stable being 4.6.8) and all of them IIRC use the mono-3 branch now.

You might want to try

fi.CreationTime = timeCreate.TimeOfDay;

as well
