Hi core-libs-dev,
At Google, we often use microsecond precision for instants/durations (probably because of historical reasons). Therefore, we have a handful of static utility functions for creating/converting java.time types and microseconds:
public static Duration ofMicros(long micros) public static long toMicros(Duration duration)
public static Instant ofEpochMicros(long micros) public static long toEpochMicros(Instant instant)
Duration includes APIs for creating/converting to days, hours, minutes, seconds, millis, and nanos. Instant includes APIs for creating/converting to seconds and millis. Micros are noticeably absent.
I'm curious how these sets of units were chosen or decided upon? I understand that the line must be drawn somewhere (or else someone may come along asking for centisecond support), but I'm curious as to the rational.
Thanks!
