'Creates a new object corresponding to the instant in time this
method is called.
.. note::
"Now" is determined using the `~datetime.datetime.utcnow`
function, so its accuracy and precision is determined by that
function.  Generally that means it is set by the accuracy of
your system clock.
Returns
nowtime
A new `Time` object (or a subclass of `Time` if this is called from
such a subclass) at the current time.'
