Select this to include the timestamp in the remote directory.

The timestamp is the date of build. If this publisher is being used during a promotion, then the timestamp is that of the build that is being promoted.
This setting turns the remote directory option into a java SimpleDateFormat.
The SimpleDateFormat(SDF) uses letters to represent components of the date, like the month, year, or day of the week. Click here for more information about the date patterns.
As the SDF reserves all of the letters [A-Z][a-z], any that you want to appear literally in the directory that is created will need to be quoted.

Some examples follow - all examples are based on a build with a timestamp of 3:45 pm and 55 seconds on the 7th November 2010.
