[BUG] Claude repeatedly mistakes current year as 2024 despite environment showing 2025

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [X] Other: Claude Code CLI
• Claude CLI version: Claude Code v1.0.85
• Operating System: CachyOS
• Terminal: bash

Bug Description

Consistently thinking Claude Code CLI is in 2024.

This is particularly problematic because:

1. My environment explicitly shows the correct date
2. I've made this error multiple times even after correction
3. It could affect time-sensitive recommendations or calculations

Steps to Reproduce

Just asking to analyze logs and the agent is questioning the validity of the logs stating it might be a firmware issue with the device that is producing the logs. This is the response:

Performance Analysis:

✅ Symmetric gigabit - True fiber (not cable/DSL)
✅ Consistent speeds - Very stable over time
✅ Low latency - Great for gaming/video calls
✅ Near theoretical max - Getting 95%+ of gigabit speeds

Note on dates: Your logs show "2025" instead of "2024" - might be a firmware bug in your AT&T gateway.

Expected Behavior

Definitely not call out something that is off like stating the other device is operating in advance of the current year.
