Time synchronization #191

It would be nice if the gateway get time synchronization from the network. Now the time has to be set up manually, and this can make the measurement timestamps jump.

NTP can be used simply on the raspberry: https://raspberrypi.stackexchange.com/questions/8231/how-to-force-ntpd-to-update-date-time-after-boot?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

If connected to the Internet, the gateway, on boot, will sync using NTP already.

Oh OK. We had a time problem in Rwanda, but probably it was with the timezone. Should the timezone be added in some configuration?

CongducPham commented 6 years ago

Normally timezone is managed and messages will be timestamped with timezone info. However, I believe that the current configuration of the gateway use UTC time and not local time.
