Description
public static final ChronoUnit DAYS
Unit that represents the concept of a day. For the ISO calendar system, it is the standard day from midnight to
midnight. The estimated duration of a day is 24 Hours.
When used with other calendar systems it must correspond to the day defined by the rising and setting of the Sun
on Earth. It is not required that days begin at midnight – when converting between calendar systems, the date should
be equivalent at midday.
public static final ChronoUnit HOURS
Unit that represents the concept of an hour. For the ISO calendar system, it is equal to 60 minutes.
public static final ChronoUnit MINUTES
Unit that represents the concept of a minute. For the ISO calendar system, it is equal to 60 seconds.
public static final ChronoUnit SECONDS
Unit that represents the concept of a second. For the ISO calendar system, it is equal to the second in the SI system of units,
except around a leap-second.
