I'm not too familiar with this. What do you mean by plus the max value of long for nanos?

I see that the MAX is 1000000000-12-31T23:59:59.999999999Z. Does this mean that this is essentially where jtInstant.getNano() and jtInstant.getEpochSecond() are both Interger.MAX_VALUE?

Instants and Durations have two components: the seconds part and the nanos part, both being long for Duration, and long for seconds + int for nanos in Instant.

Does this mean that this is essentially where jtInstant.getNano() and jtInstant.getEpochSecond() are both Interger.MAX_VALUE?

Yes, but with Long.MAX_VALUE for the seconds part instead.

Ok gotcha. I couldn't make sense of where the overflow was originally coming from since MAX_VALUE itself shouldn't trigger an overflow. If I'm understanding this correctly, it was triggered from the old way of how we were converting.

The toNanos() method was limited to Long.MAX_VALUE which has a limit of 292 years. Since Instant.MAX_VALUE has Long.MAX_VALUE for both seconds and nanos, it wouldn't be able to fit into toNanos() into a Long.MAX_VALUE as adding all the seconds + nanos would easily overfill.

Exactly.

Yes. I don't think we will ever deal with durations instants that last longer than a few hours but it's good to support the theoretical limits of these classes, even because a user may just try a max value and that may break the library.

// we use the max long value for the seconds part and an arbitrary int for the nanos part, so we

qq, any specific reason for an arbitrary value of 123 and not Long/Integer.MAX_VALUE? Perhaps we use MAX_VALUE for consistency?

No specific reason. I modified this to use the max possible nano value without overflowing the duration
