Hello,
Cool! Nice catch. I confirm - managed to reproduce this as well on my side.
I use the SDK in my local playground which is running a basic Windows 10 installation. The time server is the default time.windows.com and it was last synced on the 26th of Dec 
and of course that because of this my application did not start. I did a force sync and the application started successfully.
I will check further to see why sometimes my time is not synchronized automatically by Windows.
But yeah, thanks a lot for this 
it was really grinding my gears 
Cheers
