v0.1.7

• Improvements
  • Reduce chances of raising when something goes wrong getting the time zone
    information. For example, recover if a time zone hasn't been loaded yet and
    the cache GenServer isn't available. This fixes crashes in code that may not be
    easy to debug when there are calendar troubles.
  • Don't load a time zone more than once if multiple processes ask for the same
    one at the same time.
