I am running Android 4.4 (using custom a custom rooted system image) in the android emulator (from the command line). When trying to set the time via Settings > Date & time ("Automatic date & time" and "Automatic time zone" are disabled) i can set the time (the dialog appears and works), but the system clock is not updated.
D/ ( 1206): Setting time of day to sec=1515250620 W/ ( 1206): Unable to open alarm driver: No such file or directory
What could cause the alarm driver to be unavailable/missing and how can i fix this?
Update: I have verified that /dev/alarm is missing -- is there any way to add the missing driver without having to recompile android?
