out = NaT () ¶out = NaT (sz) ¶“Not-a-Time”. Creates missing-valued datetime 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 NaTs. Doing arithmetic with a NaT and
any other value results in a NaT.
NaT currently cannot create NaT arrays of type localdate. To do that,
use localdate.NaT instead.
