#### 8.2.10.26 datetime.NaT ¶

Static Method: `out =` datetime.NaT `()` ¶
Static Method: `out =` datetime.NaT `(sz)` ¶

  “Not-a-Time”: Creates NaT-valued arrays.

  Constructs a new `datetime` array of all `NaT` values of the given size. If no input sz is given, the result is a scalar `NaT`.

  `NaT` is the `datetime` equivalent of `NaN`. It represents a missing or invalid value. `NaT` values never compare equal to, greater than, or less than any value, including other `NaT`s. Doing arithmetic with a `NaT` and any other value results in a `NaT`.
