Specified by:

instant in class Clock

hashCode

public int hashCode()

Overrides:

hashCode in class Clock

equals

public boolean equals(Object obj)

Overrides:

equals in class Clock

toString

system

public static NanoClock system(ZoneId zone)

This clock is based on the nano system clock. It uses System.nanoTime() resolution

Conversion from instant to date or time uses the specified time-zone.

The returned implementation is immutable, thread-safe and Serializable.

Parameters:

zone - the time-zone to use to convert the instant to date-time

Returns:

a clock that uses the best available system clock in the specified zone

Throws:

NullPointerException - if the given zone is null

systemUTC

public static NanoClock systemUTC()

This clock is based on the nano system clock. It uses System.nanoTime() resolution

Conversion from instant to date or time uses the specified time-zone.

The returned implementation is immutable, thread-safe and Serializable.

Returns:

a clock that uses the best available system clock in the UTC zone

Throws:

NullPointerException - if the given zone is null

systemDefaultZone

public static NanoClock systemDefaultZone()

This clock is based on the nano system clock. It uses System.nanoTime() resolution

Conversion from instant to date or time uses the specified time-zone.

The returned implementation is immutable, thread-safe and Serializable.

Returns:

a clock that uses the best available system clock in the default zone

Throws:

NullPointerException - if the given zone is null
