setTimes	back to summary
public void setTimes(FileTime lastModifiedTime, FileTime lastAccessTime, FileTime createTime) throws IOException Implements java.nio.file.attribute.BasicFileAttributeView.setTimes. Doc from java.nio.file.attribute.BasicFileAttributeView.setTimes. Updates any or all of the file's last modified time, last access time, and create time attributes. This method updates the file's timestamp attributes. The values are converted to the epoch and precision supported by the file system. Converting from finer to coarser granularities results in precision loss. The behavior of this method when attempting to set a timestamp that is not supported or to a value that is outside the range supported by the underlying file store is not defined. It may or not fail by throwing an `IOException`. If any of the `lastModifiedTime`, `lastAccessTime`, or `createTime` parameters has the value `null` then the corresponding timestamp is not changed. An implementation may require to read the existing values of the file attributes when only some, but not all, of the timestamp attributes are updated. Consequently, this method may not be an atomic operation with respect to other file system operations. Reading and re-writing existing values may also result in precision loss. If all of the `lastModifiedTime`, `lastAccessTime` and `createTime` parameters are `null` then this method has no effect. Usage Example: Suppose we want to change a file's last access time. `Path path = ... FileTime time = ... Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null);` Path path = ... FileTime time = ... Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null); Annotations @Override Exceptions IOException: if an I/O error occurs
