After Black update of my Lumia 925 Glance screen does not always display the Time , though it is always on. Try to fix this bug. Soft reset couldn't solve the problem.
Have you updated all your system apps following the update? If not, download and install an app called Lumia System Updater and use it to update all the system apps. See if that helps.

I have seen that when you see the screen in dark, after opening the flip cover a mild light is flashed but the clock remains off.
All the possibilities I have tried including auto brightness off, but no result is found. It is a bug because many suffers from it. Make the bug free by small update.
