Problem

The system prompt currently only injects the timezone:

## Current Date & Time
Time zone: Europe/London

This means the agent has to infer the current date from message timestamps (which only show YYYY-MM-DD format without the day of week). This leads to the agent confidently stating the wrong day — e.g., saying "Sunday" when it's actually Monday.

Proposed Solution

Inject the full date including day of week into the system prompt, e.g.:

## Current Date & Time
Current: Monday, 26 January 2026, 06:53 GMT
Time zone: Europe/London

This would eliminate day-of-week guessing errors entirely.

Workaround

Currently working around this by adding a note to AGENTS.md reminding the agent to run date before mentioning the day of week — but that's wasteful and easy to forget.
