How can “relative dates” be PERMANENTLY DISABLED in iOS?

How can “relative dates” be PERMANENTLY DISABLED in iOS, and iOS set to enforce displaying the full ISO8601 date in all apps?

Mail, in particular is severely crippled as a legal source of historical documentation because of this!

Can you imagine what the judge is going to think having reams of printed documents of evidence brought before him in which every document reads ‘today’, ‘tomorrow’, or ‘yesterday’, and you try to explain that, “Well, your honor, THIS ‘yesterday’ was actually 2017-05-05 18:22, when the respondent failed to pick up the children from school, yet again, as the preponderance of evidence (see these 27 email messages documenting the exact dates and times—‘yesterday’, ‘today’, ‘today’, ‘yesterday’…ad absudum infinitum!)!?!? 🤦🏻‍♂️

This is a CRITICAL FLAW in iOS, (and is mirrored im macOS, but there are hacks to “fix” macOS). I’m sure that someone thought it was very “cute” and “helpful” to give users relative dates. Having this as an OPTION would be helpful. Procrusteanly forcing this upon everyone is criminal.
