1、代码仓库
git clone github.com/wolfcw/libf…
2、安装
make && make install
3、测试
测试 一：
(1) echo '@2033-12-24 08:15:42' > /tmp/my-faketime.rc
(2) LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 \
FAKETIME_TIMESTAMP_FILE=/tmp/my-faketime.rc \
FAKETIME_DONT_RESET=1 \
bash -c 'while true ; do date ; sleep 1 ; done'
(3) 测试效果
[root@iZbp1bh3oeew2koe4ntrpyZ ~]# echo '@2033-12-24 08:15:42' > /tmp/my-faketime.rc
[root@iZbp1bh3oeew2koe4ntrpyZ ~]# LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 \
> FAKETIME_TIMESTAMP_FILE=/tmp/my-faketime.rc \
> FAKETIME_DONT_RESET=1 \
> bash -c 'while true ; do date ; sleep 1 ; done'

^C
[root@iZbp1bh3oeew2koe4ntrpyZ ~]#
测试二：
(1) 代码片段
log.info("TimeTester Application started");
new Thread(() -> {
while (true) {
log.info("LocalDateTime.now():{}", LocalDateTime.now());
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
log.info("new Date():{}", sdf.format(new Date()));
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
（2）执行命令
[root@iZbp1bh3oeew2koe4ntrpyZ home]# LD_PRELOAD=/usr/local/lib/faketime/libfaketime.so.1 FAKETIME_TIMESTAMP_FILE=/tmp/my-faketime.rc FAKETIME_DONT_RESET=1 java -jar time-tester-0.0.1-SNAPSHOT.jar
