Previous || chain could pass through invalid values causing NaN. Now explicitly checks each possible timestamp field with: - null check (field != null) - NaN check (!isNaN(parseFloat(field))) - Takes first valid numeric value found This ensures timestamps always have a valid number, defaulting to 0 if no valid timestamp field is found. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
