Setting datetime axis bounds as half days using Matplotlib

Question

I have the following plot with datetime on the x axis, but I'd like to trim the start and end times to halfway through the days.

The limit setting script is currently

ax1.set_xlim([datetime.date(2020, 9, 16), datetime.date(2020, 9, 26)])

Is there a way to alter the plot to trim to a non full day?

Solved with thanks to Mr T.

Rather than the previous code, setting the limits in the plotting code, I created an object:

lims=[np.datetime64('2020-09-16 15:00'), np.datetime64('2020-09-25 17:00')]

Which was then applied to the plotting code:

ax1.set_xlim(lims)

The resultant plot looks like this:
