gson-threeten-serialisers
What is it?
A set of GSON serialiser/deserialisers for dealing with Java 7 "three ten" backport of the java.time entities. Wherever possible, ISO 8601 string representations are used.
Note: if you are using Java 8 then you're in the wrong place - use the gson-javatime-serialisers instead.
