Is there really no way to use the new DateTime API, and ditch the multiplication by 1000L here? 116 return ldt.toEpochSecond( 117 ZoneId.systemDefault().getRules().getOffset(ldt)) * 1000L; I guess using java.util.concurrent.TimeUnit might suffice: return TimeUnit.MILLISECONDS.convert(ldt.toEpochSecond(...), TimeUnit.SECONDS); The idiomatic DateTime way I guess would be to do: return Duration.ofSeconds(ldt.toEpochSecond(), 0).toMillis(); I'll take these for a spin; properly inlined either variant might be performance neutral. It seems any difference between the second-to-millisecond conversion approaches is negligible under repeated testing[1], thus I think the preferred approach is to use be Duration.ofSeconds(..).toMillis(): http://cr.openjdk.java.net/~redestad/8066644/webrev.03

Or we go with TimeUnit, since that's already used in the same utilities for straightforward conversions:
