to_np_datetime64 converts a Java date-time to a numpy.datetime64.
danger
Avoid deephaven.time functions in query strings. Because deephaven.time provides functions that convert between Python and Java types, every call crosses the Python-Java boundary, which slows performance. For more information, see:
