time4k

Time4k

A simple replacement for the Java clock and scheduler.

Installation

In Gradle, install the ForkHandles BOM and then this module in the dependency block:

implementation(platform("dev.forkhandles:forkhandles-bom:X.Y.Z"))
implementation("dev.forkhandles:time4k")

Motivation

The Java Clock is an abstract class, which is a pain. Time4k represents the clock as a simple typealias:

typealias TimeSource = () -> Instant

The library also provides a DeterministicScheduler which is a drop-in test replacement for using a ScheduledExecutorService. You can control time and make the scheduler move forward in a controlled manner.
