Rework on the unix time converter

[vuon9]

I want the unix time converter page to be more useful.
Can you help suggesting me some ideas? /opencode

Now I have a good understanding of the current UnixTimeConverter implementation. Let me analyze what it currently does and suggest improvements.

Current features:

1. Convert between Unix timestamps and date formats
2. Multiple date formats (ISO, RFC 2822, SQL, US, EU, Compact, Custom)
3. Timezone support (source and target)
4. Relative time display ("2 hours ago")
5. "Now" button to set current time
6. Layout toggle (horizontal/vertical)

Potential improvements:

1. Add quick reference/common timestamps (common Unix timestamps)
2. Add time delta calculator (difference between two dates)
3. Add batch conversion (multiple timestamps)
4. Add date arithmetic (add/subtract time units)
5. Add epoch time conversion (different epochs)
6. Add more time units (milliseconds, nanoseconds)
7. Add preset common timestamps (start of day, end of day, yesterday, tomorrow)
8. Add human-readable duration breakdown
9. Add copy buttons for all outputs
10. Add visual calendar component
11. Add countdown/timer display
12. Add timezone offset display
13. Add UTC/local time comparison
14. Add time unit conversion (seconds to minutes/hours/days)

Let me provide a comprehensive suggestion to the user. Based on the current implementation, here are suggestions to make the Unix Time Converter more useful:

Current Features (Already Great!)

• ✓ Multiple date formats (ISO, RFC 2822, SQL, US/EU)
• ✓ Timezone conversion (source → target)
• ✓ Relative time display ("2 hours ago")
• ✓ Custom format strings
• ✓ "Now" button
• ✓ Layout toggle

Suggested Improvements

1. Time Calculator/Delta Mode

Add a comparison feature to calculate the difference between two timestamps:

• "How long until Friday 5pm?"
• "How many days between Date A and Date B?"
• Show breakdown in multiple units (X days, Y hours, Z minutes)

2. Quick Presets Panel

Add clickable preset buttons for common timestamps:

• Start of today / End of today
• Yesterday / Tomorrow
• Start of week / End of week
• Next Monday 9am
• Unix epoch (Jan 1, 1970)

3. Date Arithmetic

Allow adding/subtracting time units:

• "+ 3 days"
• "- 2 hours"
• "+ 1 week"

4. Milliseconds & Nanoseconds Support

Support different timestamp precisions:

• Seconds (10 digits)
• Milliseconds (13 digits)
• Microseconds (16 digits)
• Nanoseconds (19 digits)

5. Duration Breakdown

When showing relative time, add a detailed breakdown:

"2 days, 5 hours, 30 minutes ago"
or "In 3 hours 15 minutes"

6. Visual Time Widget

Add a mini calendar picker and analog/digital clock visualization.

7. Batch Conversion Mode

Allow input of multiple timestamps (one per line) and convert all at once.

8. Timezone Offset Display

Show clear UTC offset (e.g., "UTC+7" or "UTC-5") for selected timezones.

9. Copy All Button

Add a button to copy all formatted outputs at once (timestamp + all format variations).

10. History/Recent Conversions

Remember recent conversions for quick reference.

Which of these features would you like me to implement? I can start with any priority items, or implement multiple features at once!

/opencode what if i want all of these features, then how the page looks like? Can you wrap it up with mockup and more proper requirement?
