+ * nsSMILTimeValue class
+ *
+ * A tri-state time value.
+ *
+ * First a quick overview of the SMIL time data types:
+ *
+ * nsSMILTime -- a timestamp in milliseconds.
+ * nsSMILTimeValue -- (this class) a timestamp that can take the additional
+ * states 'indefinite' and 'unresolved'
+ * nsSMILInterval -- a pair of nsSMILTimeValues that defines a begin and an
+ * end point.
+ * nsSMILInstanceTime -- an nsSMILTimeValue used for constructing intervals. It
+ * contains additional fields to govern reset behavior.
+ * It also forms an anchor for establishing syncbase
+ * relationships.
+ * nsSMILTimeValueSpec -- a component of a begin or end attribute, such as the
+ * '5s' or 'a.end+2m' in begin="5s; a.end+2m". These
+ * objects produce nsSMILInstanceTimes and are also used
+ * in managing dependent relationships between
+ * animations.
+ *
+ * Objects of this class may be in one of three states:
+ *
+ * 1) The time is resolved and has a millisecond value
+ * 2) The time is indefinite
+ * 3) The time in unresolved
+ *
+ * There is considerable chance for confusion with regards to the indefinite
+ * state. Is it resolved? We adopt the convention that it is NOT resolved (but
+ * nor is it unresolved). This simplifies implementation as you can then write:
+ *
+ * if (time.IsResolved())
+ * x = time.GetMillis()
+ *
+ * instead of:
+ *
+ * if (time.IsResolved() && !time.IsIndefinite())
+ * x = time.GetMillis()
+ *
+ * Testing if a time is unresolved becomes more complicated but this is tested
+ * much less often.
+ *
+ * In summary:
+ *
+ * State | GetMillis | IsResolved | IsIndefinite
+ * --------------+--------------------+--------------------+-------------------
+ * Resolved | The millisecond | PR_TRUE | PR_FALSE
+ * | time | |
+ * --------------+--------------------+--------------------+-------------------
+ * Indefinite | LL_MAXINT | PR_FALSE | PR_TRUE

+// The definition of the ElementTimeControl interface differs between SMIL

+// semantics are applied as with any other instance time. In the SVG definition
+// the methods return a bool depending on the restart mode. There are some
+// cases where this is problematic.
+//
+// For example, if a call is made to beginElementAt and the resolved time
+// after including the offset falls outside the current interval then using
+// the SMIL Animation definition an element with restart == whenNotActive
+// would restart with this new instance time. The SVG definition however seems
+// to imply that in this case the implementation should ignore the new
+// instance time if the restart mode == whenNotActive and the element is
+// currently active and return false.
+//
+// It is tempting to try and determine when a new instance time will actually
+// cause a restart but this is not possible as in the meantime a new event may
+// trump the new instance time. We take a compromise of returning true and
+// false according to the SVG definition but adding the instance time to the
+// list regardless. This may produce different results to an implementation that
+// follows strictly the behaviour implied by the SVG spec.
