If Timestamp convertible, origin is set to Timestamp identified by origin. cache bool, default True. If True, use a cache of unique, converted dates to apply the datetime conversion. May produce significant speed-up when parsing duplicate date strings, especially ones with timezone offsets. The cache is only used when there are at least 50 values.

One of these arguments is infer_datetime_format. By default, it is set to False. However, by setting it to True, the method infers the format of the first timestamp string in a collection, and then tries to use that format to parse the Oct 08, 2019 · How do I convert a numpy.datetime64 object to a datetime.datetime (or Timestamp)?
