That partial transcript isn’t an exhibit, but rather part of a charging document; it’s presumably formatted to be consistent with the standards of the court in which it is filed (courts can be very picky about this stuff, requiring specific margins, typefaces, spacing, etc., and sometimes judges have their own personal rules). In addition to this charging document, the prosecution will file exhibits consisting of screenshots or some other type of transcript that is admissible as evidence.

It should have timestamps, even if it is just a charging document. I can’t imagine prefacing the names with times would be out of bounds.
