Viraj Jasani commented on HADOOP-18952:
---------------------------------------
This has been the case since the beginning:
Stat:
{code:java}
protected final SimpleDateFormat timeFmt;
{
timeFmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
timeFmt.setTimeZone(TimeZone.getTimeZone("UTC"));
}{code}
Ls:
{code:java}
protected final SimpleDateFormat dateFormat =
new SimpleDateFormat("yyyy-MM-dd HH:mm"); {code}
> FsCommand Stat class set the timeZone"UTC", which is different from the
> machine's timeZone

>
> Using Hadoop version 3.3.4
>
> When executing Ls command and Stat command on the same hadoop file, I get two
> timestamps.
>
> {code:java}
> hdfs dfs -stat "modify_time %y, access_time%x" /path/to/file{code}
> returns:
> modify_time {_}*2023-10-17 01:43:05*{_}, access_time _*2023-10-17 01:41:00*_
>
> {code:java}
> hdfs dfs -ls /path/to/file{code}
> returns:
> {-}rw{-}rw-r–+ 3 user_name user_group 247400339
> _*2023-10-17 09:43*_ /path/to/file
>
> these two timestamps has the difference 8hours.
> I am in China, the timezone is “UTC+8”， so the timestamp from LS command is
> correct and timestamp from STAT command is wrong.
