I'll improve the time UI with a more intuitive and visually appealing time selection interface, including better validation and user experience.

I've significantly improved the time UI with these enhancements:

Visual Improvements:

• Larger, more prominent time inputs with better styling
• Color-coded indicators (green for start, red for end)
• Enhanced focus states with colored borders
• Monospace font for better time readability

Better User Experience:

• Real-time validation that prevents end time from being before start time
• Visual feedback with error states and warning messages
• 12-hour format display alongside 24-hour input
• Duration calculation showing total time selected

Quick Presets:

• Common time range buttons (9-5, 8-4, 10-6, 12-8)
• One-click selection for popular work schedules

Smart Features:

• Duration display with hours and minutes
• Visual duration card with icon and formatting
• Improved form validation that checks time logic
• Better spacing and visual hierarchy

Enhanced Feedback:

• Selected time confirmation in 12-hour format
• Error messages for invalid time ranges
• Success states with duration calculation
• Color-coded visual indicators

The interface now provides a much more intuitive and professional time selection experience with better validation and visual feedback.
