 # [unreleased]
 
+## Fixed
+
+- CUC timestamp was fixed to include leap second corrections because it is based on the TAI
+  time reference. Changed the `TimeReader` trait to allow specifying leap seconds which might
+  be necessary for some timestamps to enable other API.
+
 ## Added
 
 - `From<$EcssEnum$TY> from $TY` for the ECSS enum type definitions.
