02:30 doesn't exist when the clocks go forward. 01:30 happens twice when they go back. clockworktz resolves this in TypeScript, the way Temporal does. Zero dependencies, pinned IANA tzdb, signed updates. try it in your next project

Day 7 of Training for the London Marathon 2027 A few training sessions since the last one, but just counting this one for now. Mixed it up with light weights and incline walking. Today I did 31mins on the treadmill at highest incline.

So this morning I was looking for a free interactive Data Structures and Algorithms course aimed at TypeScript developers. I could not find a good example, so I made one myself using Cursor and Grok 4.7 High. Check it out! 👇

Day 6 of Training for the London Marathon 2027 30 minute incline walk. Weight loss mode for now! I have a minor knee injury, so keeping things light and relaxed until that's fully healed. Aiming for proper regular running schedule by early December.

Running X people. Marathons or anything, reach out! 🏃 I’d like to follow (no follow back expected, though it would be nice 👌). I’m training for the 2027 London Marathon - need inspiration!
