$Date$ is Locale-specific, so causes problems when comparing source code with SVN. $Id$ is OK because it uses UTC, but it also includes the file name and last user id, so is fairly long. $Revision$ should be sufficient in general. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
