    # Because Python 3.12 now requires non-naive timezone declarations, we must change.
    #
    # ## Example:
    # ## The new way:
    # ##     datetime.now(timezone.utc).isoformat()
    # ##     Result: 2024-04-16T16:00:00+00:00
    # ## End Example
    #
    # Note that the +00:00 is appended now where we affirmatively declare the UTC
    # timezone
    #
    # As a result, we will use this function to prune away the timezone if it is +00:00
    # and replace it with Z, which is shorter Zulu notation for UTC (per Elasticsearch)
    #
    # We are MANUALLY, FORCEFULLY declaring timezone.utc, so it should ALWAYS be +00:00,
    # but could in theory sometime show up as a Z, so we test for that.
