> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: nfs

> Reporter: Brandon Li
> Priority: Minor

>
> As [~cnauroth] pointed out in HADOOP-10612, Time#monotonicNow is a more
> preferred method to use since this isn't subject to system clock bugs (i.e.
> Someone resets the clock to a time in the past, and then updates don't happen
> for a long time.)
