+Timestamps without NaNs
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``timestamps`` field of a :ref:`nwb-schema:sec-TimeSeries` should not contain ``NaN`` values, as this can lead to
+ambiguity in time references and potential issues in downstream analyses.
+
+Ensure that all timestamps are valid numerical values. If gaps in time need to be represented, consider segmenting the
+data into separate :ref:`nwb-schema:sec-TimeSeries` objects with appropriate ``starting_time`` or use the ``timestamps``
+vector to explicitly represent time gaps.
