Remarks

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 result 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.

<b>Usage Example:</b> Suppose we want to change a file's last access time.

Path path = ...
               FileTime time = ...
               Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null);
