+                    One of the ways BitBake determines whether to re-parse the
+                    main metadata is by using a checksum of the variables in
+                    the datastore of the base configuration data.
+                    There are variables that you typically want to exclude from
+                    these checksum comparisons.
+                    As an example, you would usually exclude
+                    <filename>TIME</filename> and <filename>DATE</filename>
+                    because these variables are always changing.
+                    If you did not exclude them, BitBake would never use the
+                    cache.
