Description

public boolean setLastModified​(long time)

Sets the last-modified time of the file or directory named by this abstract pathname.
All platforms support file-modification times to the nearest second, but some provide more precision
The argument will be truncated to fit the supported precision
If the operation succeeds and no intervening operations on the file take place,
then the next invocation of the lastModified() method will return the (possibly truncated)
time argument that was passed to this method.
