v0.3.1

• Bug fixes
  • Move ntpd's prints to the log. The previous prints to the console were quite
    annoying to say the least.
  • Remove the build timestamp so that nerves_time builds are reproducible.
    This is important for users that want to recreate firmware images with as
    few differences as possible. The build timestamp had restricted the earliest
    allowed time. The earliest time is now hardcoded, but can be overridden by
    application config (same with the latest possible time.)

v0.3.0

IMPORTANT: This release moves Nerves.Time to the NervesTime namespace. If
you are using the API, you will need to rename every instance of Nerves.Time
in your code to NervesTime.

• Bug fixes

  • ntpd crash detection and restart have been simplified by using
    MuonTrap.Daemon. This should fix an issue that was seen with ntpd not
    getting restarted after it crashed.
  • NervesTime.synchronized?/0 would return synchronized when changing NTP
    servers and right after restarting ntpd. It will return false now and
    switch to true when time really has been synchronized.

• Improvements

  • Simplified ntpd reporting code. No more regular expressions. Reports are
    sent via a Unix Domain socket and encoded as Erlang terms. This deleted a
    lot of string parsing code that felt brittle.
  • Added a restart delay on unclean ntpd restarts to prevent pegging public
    NTP servers. The delay is currently a minute since ntpd crashes are not
    well-understood. Luckily, this seems like a rare event.
  • Added more tests to cover NTP use

v0.2.1

• Improvements
  • Move C build products under _build. This lets you switch targets with out
    cleaning builds in between.

v0.2.0

• Added support for configuring NTP servers at runtime. Thanks to @ConnorRigby
  for sending a PR for this
• Added Nerves.Time.restart_ntpd/0 for users who know external information
  about good times to bounce the NTP daemon so that it syncs more quickly
• Fixed naming of is_synchronized/0 to be synchronized?/0. Thanks to
  @brodeuralexis for catching my slip.
