 with ambiguous time specifications during DST changes.
 
 
+Postponement
+============
+
+The implementation has turned out to be exceedingly complex, due to having to
+convert back and forth between the local time and UTC during arithmetic
+and adjusting the DST for each arithmetic step, with ambiguous times being
+particularly hard to get right.
+
+This is likely to become much easier if the UTC timestamp is stored internally
+and used for all arithmetic, and an investigation into changing the
+``datetime()`` object to use UTC internally should be done.
