What is Instant in Java?

In Java, the Instant class is part of the java.time package, which was introduced in Java 8. It represents a specific moment on the timeline in UTC (Coordinated Universal Time) with nanosecond precision. The Instant class is immutable and can be used to model a point in time anywhere in the world.

Unlike date-time classes that are tied to a timezone (like ZonedDateTime), an Instant is always expressed in terms of UTC and does not carry any timezone information. This makes it ideal for capturing timestamps.
