There’s some unexpected behaviour with MMM as a formatter, which is that it’s not always 3 characters long and differ subtle by locale.

Notably on the JVM if your locale is en-GB every month is 3 chars: Jan, Feb, Mar, etc. until you get to September which is Sept.

In en-US it’s just Sep.

Of course, if you don’t specify the locale in code, it will choose the system default leading to lovely region specific exceptions for your servers in Ireland and England.

Using different locales based on region for your servers is in itself an insane decision.

It’s the default on many non-AWS providers.
