It looks like the issue only manifests for some time zones.
TZ=Europe/London sbt "core/IntegrationTest/testOnly -z com.github.mjakubowski84.parquet4s.FilteringSpec"- Success.TZ=Europe/Berlin sbt "core/IntegrationTest/testOnly -z com.github.mjakubowski84.parquet4s.FilteringSpec"- Success.TZ=Europe/Warsaw sbt "core/IntegrationTest/testOnly -z com.github.mjakubowski84.parquet4s.FilteringSpec"- Failure (1900-01-01T00:58:08 was not equal to 1900-01-01T00:34:08).TZ=Europe/Moscow sbt "core/IntegrationTest/testOnly -z com.github.mjakubowski84.parquet4s.FilteringSpec"- Failure (1900-01-01T00:04:25 was not equal to 1900-01-01T00:34:08).

Ha!
Europe/Warsaw is treated by JVM (?) as the timezone used in Polish Commonwealth several hundred years ago :D

So, it is actually a bug in Java: https://stackoverflow.com/questions/47823081/java-sql-timestamp-wrong-time-parsing
In order to fix, one must avoid using Timestamp.valueOf or similar

Well, yeah :) Switching zeroDate to a more recent date (like LocalDate.of(2000, 1, 1)) works for all the time zones above.
