World Clock

World Clock Skill

Get the current time anywhere in the world and convert times between timezones. Useful for scheduling across timezones, checking times in other cities, and handling daylight saving time.

When to Use

• User asks "What time is it in [city]?"
• User needs to convert time between timezones
• User is scheduling a meeting across timezones
• User asks about daylight saving time
• User asks when business hours start/end in another timezone

Available Operations

1. Current Time: Get the current time in any timezone
2. Time Conversion: Convert a specific time from one timezone to another
3. DST Information: Check if a location is currently in daylight saving time
4. Multiple Timezones: Show current time in several locations at once

Instructions

When a user asks about time or timezones:

Step 1: Identify the Request Type

• Current time query: "What time is it in Tokyo?"
• Conversion query: "If it's 3pm in New York, what time is it in London?"
• Scheduling query: "When should I schedule a call for 9am PST for someone in Berlin?"

Step 2: Get Timezone Identifier

Use the WorldTimeAPI with the appropriate timezone identifier.

API Endpoint:

Copy code
https://worldtimeapi.org/api/timezone/{Area}/{Location}

Step 3: Make the API Call

Example - Get Tokyo time:

Copy code
https://worldtimeapi.org/api/timezone/Asia/Tokyo

Example - Get New York time:

Copy code
https://worldtimeapi.org/api/timezone/America/New_York

Step 4: Present Results

Format clearly with:

• Current local time (12-hour and 24-hour format)
• Day of the week and date
• Timezone abbreviation (PST, EST, JST, etc.)
• UTC offset
• Whether DST is active

API Response Format

The WorldTimeAPI returns:

jsonCopy code
{
  "abbreviation": "EST",
  "datetime": "2024-01-15T14:30:00.123456-05:00",
  "day_of_week": 1,
  "day_of_year": 15,
  "dst": false,
  "dst_offset": 0,
  "timezone": "America/New_York",
  "unixtime": 1705343400,
  "utc_datetime": "2024-01-15T19:30:00.123456+00:00",
  "utc_offset": "-05:00",
  "week_number": 3
}

Key fields:

• datetime: Current local time with offset
• abbreviation: Timezone abbreviation (EST, PST, etc.)
• utc_offset: Offset from UTC
• dst: Whether daylight saving time is active
• day_of_week: 0=Sunday, 1=Monday, etc.

Examples

Example 1: Current Time Query

User asks: "What time is it in Tokyo?"

1. Call: https://worldtimeapi.org/api/timezone/Asia/Tokyo
2. Response format: "It's currently 10:30 PM JST (Japan Standard Time) in Tokyo. That's Monday, January 15, 2024. UTC offset: +09:00"

Example 2: Time Conversion

User asks: "If I schedule a call for 3pm Eastern, what time is that in London?"

1. Get current UTC offset for both timezones
2. Calculate: Eastern (EST) is UTC-5, London (GMT) is UTC+0
3. Difference: 5 hours ahead
4. Response: "3:00 PM Eastern = 8:00 PM GMT in London"

Example 3: Multi-Timezone Display

User asks: "Show me the time in New York, London, and Tokyo"

1. Call all three timezone endpoints
2. Present in a table format:

   City	Local Time	Date
   New York	2:30 PM EST	Mon, Jan 15
   London	7:30 PM GMT	Mon, Jan 15
   Tokyo	4:30 AM JST	Tue, Jan 16

Example 4: Meeting Scheduling

User asks: "I need to find a time that works for LA, New York, and Berlin"

1. Get current times for all three
2. Note offsets: LA (PST -8), NY (EST -5), Berlin (CET +1)
3. Find overlap during business hours (9am-6pm local)
4. Suggest: "9:00 AM Pacific = 12:00 PM Eastern = 6:00 PM Berlin"

Handling Edge Cases

City Not in List

If user mentions a city not in the common list:

1. Try to find the nearest major city in the same timezone
2. Or search for the country's timezone
3. Note any uncertainty in the response

Daylight Saving Time

DST changes dates vary by country:

• US/Canada: 2nd Sunday March, 1st Sunday November
• Europe: Last Sunday March, Last Sunday October
• Australia: 1st Sunday October, 1st Sunday April (opposite hemisphere)
• Japan, China, India: No DST

Always check the dst field in the API response.

Date Line Crossing

When converting across the International Date Line, the date may change:

• Tokyo is 14 hours ahead of Los Angeles
• Monday 10pm in LA = Tuesday 12pm in Tokyo

Notes

• WorldTimeAPI is completely free with no API key required
• Rate limit: 1 request per second
• Times are accurate to the second
• API automatically handles DST transitions
• For offline use, basic conversions can be done with UTC offset math
