to_np_datetime64

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:

• Time in Deephaven
• Java/Python boundary crossings

Syntax

to_np_datetime64(dt: Union[None, Instant, ZonedDateTime]) -> numpy.datetime64

Parameters

Parameter	Type	Description
dt	Union[None, Instant, ZonedDateTime]	A Java date-time to convert to a numpy.datetime64. If None is provided, None is returned.

Returns

Returns a numpy.datetime64.

Examples

from deephaven.time import dh_now, to_np_datetime64

instant = dh_now()

np_dt = to_np_datetime64(instant)
