“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
.
