Hi Marcus,
I no longer have the development environment, so if you can do the adjustments
to the fix yourself, that would be much appreciated!

> Currently, Apache Cassandra generates invalid JSON for the "duration" type.
> cqlsh> CREATE KEYSPACE ks1 WITH REPLICATION = \{ 'class' : 'SimpleStrategy',
> 'replication_factor' : 1 };
> cqlsh> CREATE TABLE ks1.data (id int, d duration, PRIMARY KEY (id));
> cqlsh> INSERT INTO ks1.data (id, d) VALUES (1, 6h40m);
> cqlsh> SELECT JSON d FROM ks1.data WHERE id = 1;
> [json]
> --------------
> \{"d": 6h40m}
> That is, the duration is not quoted and is therefore invalid according to
> [https://jsonlint.com/,] for example.
>
> Fix the problem by quoting the formatted duration type properly:
> cqlsh> INSERT INTO ks1.data (id, d) VALUES (1, 6h40m);
> cqlsh> SELECT JSON d FROM ks1.data WHERE id = 1;
> [json]
> ----------------
> \{"d": "6h40m"}
> (1 rows)
>
> The problem is fixed by the following patch:
> [^0001-Fix-SELECT-JSON-formatting-for-the-duration-type.patch]
