-For open ended display you can just specify a start date. 
-To start immediately and end on a specific date you can just specify a stop date.
+For open ended display you can just specify a start date.  To start
+immediately and end on a specific date you can just specify a stop
+date.
+
+The start and stop date use the convert_date tag, so you can use any
+format acceptable by that tag to specify your start and stop
+dates.	(See convert_date documentation for details.)
+
+If the 'timevar' parameter is provided, instead of the current time
+look first in the CGI and the Scratch variables with the provided name
+for a date string to convert.  This allows you to provide a way to
+test this behavior outside of the wall-clock time and see the actual
+behavior at a specific time.
 
-The start and stop date use the convert_date tag, so you can use any format acceptable by that tag to specify your start and stop dates. (see convert_date documentation)
+You can also use the 'adjust' parameter, which will pass its argument
+directly on to the convert_date calls; this can be used to localize
+the timezone relative to the server time.
