commit 6fba3db some, but not all, config props said in their description what units they were in (either milliseconds or seconds). The ones that had this missing are now fixed. The descriptions for those (which were all units of seconds) now say they are specified in seconds.
Verified on rhq4 release build (Version: 4.0.0 Build Number: db0c817) The Configuration tab displays the units in required properties ( milliseconds or seconds). Verified in all sections of the RHQ Agent->Configuration tab. Marking as verified.
Bookkeeping - closing bug - fixed in recent release.
