Major Description
The touch command was added by HADOOP-9214, but the usage instructions and docs have never aligned with the code.
The code uses a timestamp format of:
new SimpleDateFormat("yyyyMMdd:HHmmss");
But the docs indicate it should be yyyyMMddHHmmss.
While I believe the format in the docs is better, tools or applications may be relying on the old format now, so I suggest we simply update the docs and usage, and improve the error message if the wrong format is used.
