Tsz-wo Sze updated HDDS-7911:
-----------------------------
Description:
OM uses Time.now() for creation time and modification time. Time.now()
(org.apache.hadoop.util), which calls System.currentTimeMillis(),
-
[https://docs.oracle.com/javase/8/docs/api/java/lang/System.html#currentTimeMillis--]
depends on the local time zone setting. It may cause problems when moving an
Ozone image from one machine to another machine with different time zone
settings. Instead, we should use Instant.now()
- [https://docs.oracle.com/javase/8/docs/api/java/time/Instant.html#now--]
which uses UTC time-zone.
> Replace Time.now() with Instant.now()
