[postmodern-devel] Regression in handling integer dates and timestamps

[Marijn Haverbeke]

It could be that simple-date is being accidentally (or intentionally)
loaded. Could you check whether the :simple-date package is present?
That will register handlers for serializing date and time values,
which might cause the behaviour you describe. These two patches might
be to blame:
