This error has been addressed in lau/tzdata#83 and is in v1.0.1

We should update our tzdata dependency

from: {:tzdata, "~> 0.1.8 or ~> 0.5 or ~> 1.0.0"},

to: {:tzdata, "~> 0.1.8 or ~> 0.5 or ~> 1.0.1"}

It is already updated in master, but it is easily addressed in your own project by running mix deps.update tzdata
