This title really doesn't fit what the submission did actually.

The submitter made a basic MCP function that returns the current time, so... Claude knows the current time. There is nothing about sundials and Claude didn't somehow build a calendar in any shape or form.

I thought this was something original or otherwise novel but it's not... it's not complex code or even moderately challenging code, nor is it novel, nor did it result in anything surprising... it's just a clickbaity title.

Fair point on the metaphor—let me be concrete.

What’s new here isn’t just exposing `current_datetime()`. The server also gives the model tools to reason about time:

  (1) time_difference(t1, t2)  – exact gaps with human wording  

  (2) timestamp_context(t)      – “weekend evening”, “workday morning”  

  (3) time_since(t)             – “2 h ago, earlier today”  

I also request that Claude ask for time at every turn, which creates a timeseries that is parallel to our interactions. When Claude calls these every turn it starts noticing patterns (it independently labelled our chat as a three-act structure). That was the surprise that prompted the title.

Ask Claude “what patterns do you see so far?” after a few exchanges.

If you still find it trivial after trying, happy to hear why—genuinely looking for ways to push this further. Thanks for the candid feedback.

Finding a good title is really hard. I'd appreciate any advice on that. You'll notice I wrote the article several weeks ago, and that's how long it took me to figure out how to pitch on HN. I'd appreciate any feedback to improve. Thanks!

Clearly an honest mistake but yeah a metaphor probably shouldn't be used in a title like this, since many readers will take it literally. I've changed the title now to language from the article.

(Submitted title was "Show HN: I gave Claude a sundial and it built a calendar")

Thanks so much for the title change! I completely understand.

I apologize to the community for the mistake. I appreciate this feature of this community's discourse. I'll remember to use literal, precise language in the future.

Your reworded title fits perfectly — thank you!

That's MCP/AI libraries for ya.

Give it a picture of the Sun at the same time every day, and lets see if it comes up with a calendar from that.

Agreed. I’m tired of these ridiculous claims by people just trying to hype up LLMs. Flagging this article.

I'm sorry for choosing an inappropriate title — that was my bad, and fortunately @dang helped correct this mistake.

Aside from the title, what claims do I make that you find ridiculous?
