I want to filter my images in Lightroom by capture time (not date) but can't work out how

I have 1000 photos of a scene taken over four years. I would like to find all the pictures taken at the same time of day, for e.g. 8am. I feel sure this must be possible in Lightroom, but I only seem able to filter by date, month or day, and not time. Can anyone help? Is it possible to do this?

Many thanks.
