Why is my Nexus 5 system clock slow by 18 minutes?

[AC Question]

I have a nexus 5, which I bought from google two years ago. The clock started running slow about a month ago. I installed the latest update to android, but the clock is still slow. Does anybody know why this might be happening?

Is your phone set to get date and time from the network? If so then contact your carrier
