Ever since I have updated my Nexus 5 to Marshmallow, there have been constant issues with auto update of date and time. Sometimes when the phone is idle, it decides to not update the time displayed. The worst is when the alarm doesn't ring because of this, and I end up being late or unaware of it, until I come across some other source of time. This is more than just a little annoying, its terribly inconveniencing. I have already tried correcting it and enabling auto update of date/ time and time zone multiple times, but no luck. Is anyone else facing the same issue? Need help!
