Microseconds can be a convenient level of precision for many computing operations and should be supported directly in java.time Instant and Duration.

Nanoseconds provide greater resolution but require conversions and rounding to work smoothly with microsecond precision numbers.
The request was made on core-libs and a sample of the frequency of use of various Instant and Duration methods was provided.
