Hmmm... that's a tough one. But one quirky solution may be the following, though the exif data will not be accurate.
Using Gwenview, you can not only edit exif data, but you can import exif data from other images to those which do not have exif data, or to change the existing data.
So... maybe you can use one image as a reference and import its exif data into all of the other images, then just modify the time of day without having to modify the date. If both cameras being used were the same model and and set to the same configuration, this would work very well. Except, of course, exposure time and aperture settings will not show accurately, etc. If the cameras are different and/or were set to different configurations, the modified/imported exif data will show completely b.s. data...
I will keep looking for an exif editor which can do batch jobs... I could use that myself.
