[luoy1991]

execution environment

docker run -it --name mytest -d registry.cn-shanghai.aliyuncs.com/lvgu/python3:latest
jdk-8u251-linux-x64.tar.gz
libfaketime master branch

test.jar code

package test;

import java.time.*;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;

public class a {
private static final int NO_DELAY = 0;

public static void main(String[] args) {
Runnable printCurrentDateTime = () -> System.out.println(LocalDateTime.now());

Executors
  .newSingleThreadScheduledExecutor()
  .scheduleAtFixedRate(printCurrentDateTime, NO_DELAY, 1, TimeUnit.SECONDS);

}
}

create any file with December 24th, 2009, 12:34:56 as timestamp

touch -t 0912241234.56 /app/my-demo-file.tmp

run test.jar printing the current time

LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 \
FAKETIME='%' FAKETIME_FOLLOW_FILE=/app/my-demo-file.tmp \
FAKETIME_DONT_FAKE_MONOTONIC=1 \
FAKETIME_DONT_RESET=1 \
java -jar test.jar
