I wouldn’t say local time is superfluous, as it gives context.
If a historic event occurred at 0300 on Feb 15th, there’s a significant amount of information in knowing the local time. Was it 3am in London, when most people would be asleep. Or was it 7pm Friday night In San Francisco when people were on Valentine's dates, or was it 3pm on Saturday afternoon when people were having a bbq.
If you were to write “the accident occurred at 0300 UTC” then that would imply something very different depending on what the local time was at the time.
How about “the shop opened at 9am every day, without fail”.
Far more useful than “the shop opened at 1600UTC for half the year and 1700UTC for the other half”
Moreover, you don’t want the recorded local time to change just because the tz database is being updated.
In theory historic times wouldn’t change as t data would be updated before the change.
In reality that’s not always the case.
