-``time`` [ ``>`` min_value ]
+``time``
     Time fields behave like ``param`` fields, but need special treatment because
     the underlying value is 64-bits and so two registers need to be written.
 
-    If desired a minimum valid value can be specified as `min_value`.  This will
-    prevent the writing of values less than this value and can be read as the
-    ``.MIN`` attribute.
-
 ``bit_out``
     This identifies an output bit.
