Class PackedLocalTime

java.lang.Object

tech.tablesaw.columns.times.PackedLocalTime

public class PackedLocalTime
extends Object

A localTime with millisecond precision packed into a single int value.

The bytes are packed into the 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)
