✨ Why Time Service?

🎯 Complete Solution

Time Service provides 8 comprehensive tools covering every time-handling scenario:

• ✅ Time queries - Current time, timestamps, multiple timezones
• ✅ Time calculations - Add/subtract time, calculate differences
• ✅ Timezone operations - Convert between any timezones
• ✅ Business scenarios - Calculate business days, find next occurrences

🚀 Killer Features

🔄 Batch Operations Query multiple timezones in one call - reduce API requests and get instant global time overview:

One call → All timezones with UTC offsets

📅 Business Day Intelligence Automatically skip weekends when calculating deadlines - perfect for project management:

"Add 5 business days to today" → Automatically excludes weekends

⏰ Smart Scheduling Find next occurrence with flexible conditions:

"Next Monday at 2pm" ✓
"Next 15th of the month" ✓
"Next Friday at 14:00" ✓

🎨 Flexible Formatting 4 built-in formats plus custom configurations:

• ISO 8601: 2024-01-15T10:30:00Z
• Unix timestamp: 1705315800
• Human-readable: Monday, January 15, 2024 at 10:30:00 AM
• Custom: Any format you need

💪 Production Ready

• ✅ 100% Test Coverage - 115 comprehensive test cases
• ✅ Fully Typed - Complete TypeScript type system
• ✅ Well Documented - Clear examples and guides
• ✅ Zero Installation - Use directly with npx/bunx

🎯 Usage Examples

Real-World Scenarios

Scenario 1: Global Team Coordination

User: "What time is it in our offices in New York, London, and Tokyo?"

Time Service: Uses get_multiple_timezones
→ Returns all three times with UTC offsets in one response

Scenario 2: Project Deadline Calculation

User: "If we start today, what's the date 10 business days from now?"

Time Service: Uses get_business_days
→ Automatically skips weekends, returns exact date

Scenario 3: Meeting Scheduling

User: "Convert 2pm EST to Tokyo time"

Time Service: Uses convert_timezone
→ Handles daylight saving automatically

Scenario 4: Recurring Event Planning

User: "When's the next Monday at 9am?"

Time Service: Uses next_occurrence
→ Finds exact date and time

API Examples

Get time in multiple timezones:

{
  "name": "get_multiple_timezones",
  "arguments": {
    "timezones": ["America/New_York", "Europe/London", "Asia/Tokyo"],
    "format": "readable"
  }
}

Calculate business days:

{
  "name": "get_business_days",
  "arguments": {
    "startDate": "2024-01-15T00:00:00Z",
    "days": 5,
    "excludeWeekends": true
  }
}

Find next occurrence:

  "name": "next_occurrence",
  "arguments": {
    "dayOfWeek": 1,
    "time": "14:00"
  }
}
