"""

|
Tests for timezone support (hermes_time module + integration points).
|
|
|
|
Covers:
|
|
- Valid timezone applies correctly
|
|
- Invalid timezone falls back safely (no crash, warning logged)
|
|
- execute_code child env receives TZ
|
|
- Cron uses timezone-aware now()
|
|
- Backward compatibility with naive timestamps
