ZonedDateTime is a class in Java's `java.time` package, introduced in Java 8, that represents a date-time with a time-zone in the temporal resolution of nanoseconds. It is an immutable value type, meaning once a ZonedDateTime object is created, its value cannot be changed.

A ZonedDateTime object consists of three main components: a local date-time, a time-zone, and a chronologically valid offset from UTC. The local date-time represents the year, month, day, hour, minute, second, and nanosecond without any time-zone information. The time-zone, such as "America/New_York" or "Europe/London", provides the rules for determining the offset from UTC. The offset is the difference between local time and Coordinated Universal Time (UTC) at a specific moment.

ZonedDateTime is particularly useful for representing points in time that are unambiguous globally. For instance, if you need to schedule an event that occurs at a specific time in a particular city, ZonedDateTime is the appropriate class to use. It handles the complexities of daylight saving time and other time-zone variations automatically.

Common operations with ZonedDateTime include creating instances from various sources like other temporal objects, parsing strings, and performing date-time arithmetic such as adding or subtracting durations. It also allows for conversion to and from other temporal types like `Instant` and `LocalDateTime`. This class is a fundamental part of the modern Java date and time API, promoting robust and accurate handling of temporal data.
