This might just be a weird blip on AWS. Is anyone seeing this on other infrastructure as well?

[lau]

What version of Tzdata are you using?

[schnittchen]

D'uh, forgot to mention the obvious! I'm a bit behind on 0.5.20.

Since I'm seeing this today for the first time, master could be affected as well.

I'm sure somebody will comment here if that is the case.

[lau]

It looks like it is not just you. The new version of the tzdata (2019b) broke the Tzdata implementation: It has an entry for "Apr Sun>=25" - a Sunday in April on the 25th or later. But in 1932 there was no Sunday on or after the 25th of April in April. The first Sunday after that was on May 1st. I will release a fix.

[lau]

New releases are out with a fix:

• 1.0.1 if you are using Elixir 1.8+
• 0.5.21 for older versions of Elixir

Thank you @lau for your awesome work!
