Class PackedLocalDateTime

  • public class PackedLocalDateTime
extends PackedInstant
    A short localdatetime packed into a single long value. The long is comprised of an int for the date and an int for the time

    The bytes are packed into the date int as: First two bytes: short (year) next byte (month of year) last byte (day of month)

    The bytes are packed into the time int as First byte: hourOfDay next byte: minuteOfHour last two bytes (short): millisecond of minute

    Storing the millisecond of minute in an short requires that we treat the short as if it were unsigned. Unfortunately, Neither Java nor Guava provide unsigned short support so we use char, which is a 16-bit unsigned int to store values of up to 60,000 milliseconds (60 secs * 1000)
