Start ntp on network connection on nerves

check this blog post for a good description of NTP. All Systems Go: Creating your own startup checks with Nerves - DockYard

Linux stores time in utc, so you shouldn’t have to worry much about timezones i don’t think. Timex has support for Timezones also. There are some things to account for for Timex to work properly with Nerves though.

Hi @adrian, did you tried

{:nerves_ntp, github: "evokly/nerves_ntp", ref: "4b6f3e055d8f21c8821d6ecfaaafda77480fd2b9"}

? It works for me (without any additional configuration) via ethernet interface.

Does this imply that the hex releases are not functional?

Yes it was made a long time ago, and has since been abandoned. Ntp is so simple, I don’t think you need a extra library for it.

thanks @ConnorRigby it works! I was getting crazy with supervisors that didn’t work. I was about to fork it.

Do you recommend to set up ntp in a genserver instead of using this library? I don’t like the idea of having this dependency. How would you do it? same way as this library or maybe there is another approach?

Thanks!

That link I posted above actually uses code that I wrote for a project. If I remember correctly, most of that library borrow open source code I wrote also.
