Yeap, you are right.

    from datetime import datetime
    import humanize

    d1 = datetime.fromisoformat("2026-10-08T14:37:21Z".replace("Z", "+00:00"))
    d2 = datetime.fromisoformat("2026-10-08T13:51:36Z".replace("Z", "+00:00"))

    print(humanize.naturaldelta((d1 - d2) / 400 * 1830400))

So, supposing, that each step take about as long as the others, it's a fake.
