What I'm hoping will appear is a document that can be treated as a standard (preferably at a formal standards body of some kind). With the changes to Java, I used UTC-SLS (linear over 1000secs). But I deliberately left open the possibility for Java to adopt any future standard for smearing that emerged. https://docs.oracle.com/javase/10/docs/api/java/time/Instant.html Stephen _______________________________________________ LEAPSECS mailing list [email protected] https://pairlist6.pair.net/mailman/listinfo/leapsecs
