java.time.OffsetDateTime.now().format(DateTimeFormatter.ISO_DATE_TIME) on OpenJDK 15 (build 36) on Linux has a 9 digit precision after the second:
2020-10-20T13:23:03.079208368+02:00
But the same command on macOS (same JDK version) only has 6 digits:
2020-10-20T13:19:19.299050+02:00
JDK 14 on both Linux and macOS also only use 6 digits.
Shouldn't the precision be identical across architectures on the same JDK version?
