> As noted in that issue, the `ChronoField.INSTANT_SECONDS` currently is initialized to have a minimum and maximum values of `Long.MIN_VALUE` and `LONG.MAX_VALUE` respectively. However, `java.time.Instant` only supports `-31557014167219200L` and `31556889864403199L` as minimum and maximum values for the epoch second.

This commit also introduces a test to verify this change. This new test method as well as existing tests in tier1, tier2 and tier3 continue to pass with this change.

Given that this is a observable change through a public API, I think a csr will be needed for this. I'll draft one shortly.
