nssjson is a library that forks the Python JSON library simplejson and adds serialization and deserialization of datetime, date, and time objects. It keeps the same dumps()/loads() interface as the standard json module while automatically converting date and time values to ISO 8601 strings, and it also provides a C acceleration extension. This page also collects a list of other Python JSON libraries.
