There are two different Time Tables types in AMDA - common (shared) and private (my). My Time Tables are visible to the owner only while Shared Time Tables are open to the whole community.
Time Tables can be generated by DataMining module, or you may create them manually during Interactive Plot Session, or upload from your local machine or from URL. All your time tables are stored in your WS and can be used as input times for AMDA modules.
To access the TimeTable context menu right click the node in the TimeTable subtree.
Note that menu depends on the type of the node clicked (root, folder, leaf..).
Edit TimeTable context menu item (or double click the time table name) opens Manage TimeTables module.
