问HN：为什么Claude或ChatGPT不显示消息时间戳？
请去查看你与Claude或ChatGPT在他们的聊天应用中进行的任何对话，并询问他们最后一条消息发送的时间，你会发现他们无法看到聊天记录中任何消息的时间戳。他们可能会猜测或虚构一个答案，但通常会大相径庭，如果你进一步询问，他们应该会承认根本看不到时间戳，他们只知道当前时间。我还注意到，如果你在多天内继续对话，它并不知道消息之间已经过去了几天。
——
我：自你最后一条消息以来过去了多少时间？
Claude：
我没有办法测量我的消息之间的间隔——在轮换之间我没有时钟在运行，我们的对话中没有任何东西为我标记消息的时间戳。所以我无法告诉你自我上次回复以来过去了多少时间。可能是几秒，也可能是几天。
如果有用的话，我可以查看当前时间，但那只会告诉你<i>现在</i>的时间，而不是我上次写作以来的间隔。
——
这对我来说非常奇怪，似乎是这个产品的一个明显缺陷，但两家主要的人工智能公司都在这样做，并没有实施显而易见的解决方案来显示消息时间戳。有没有人知道他们为什么不这样做？

Go to any conversation you’ve had with Claude or ChatGPT in their chat apps and ask them what time they sent their last message, and you’ll find they don’t see timestamps for any of the messages in your chat history. They might guess or hallucinate an answer but they’ll be wildly off and if you probe further they should admit they don’t see timestamps at all, they only know the current time. I’ve also noticed generally that if you pick up conversations over multiple days, it doesn’t know that days have passed in between messages.<p>——<p>Me: How much time has passed since your last message?<p>Claude:
I don't have a way to measure the gap between my messages—I don't have a clock running between turns, and nothing in our conversation timestamps the messages for me. So I can't tell you how much time has passed since my last reply. Could've been seconds, could've been days.<p>If it's useful, I can check the current time, but that would only tell you <i>now</i>, not the interval since I last wrote.<p>——<p>This is very bizarre to me and seems like an obvious flaw in the product, but both major AI companies are doing this and not implementing the obvious solution of surfacing message timestamps. Does anyone know why they don’t do this?
