Chronos

Timezone and datetime conversion service through the Polymer Pay proxy. Get current time for any timezone, convert datetimes between timezones, and retrieve supported IANA timezone lists.

Authentication

All requests route through the Polymer Pay proxy and require an API key header:

{
  "headers": {
    "Content-Type": "application/json",
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

Base URL: https://pay.polymerlabs.org/proxy/https/mavs-agent-army.fly.dev/api/chronos/api

Common Operations

Get Current Time

Retrieve the current date and time for any IANA timezone.

Pricing: $0.005

{
  "method": "GET",
  "url": "https://pay.polymerlabs.org/proxy/https/mavs-agent-army.fly.dev/api/chronos/api/now?timezone=America/New_York",
  "headers": {
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

Parameters:

• timezone (required): IANA timezone identifier (e.g., America/New_York, Europe/London, Asia/Tokyo)

Response fields:

• datetime: ISO 8601 formatted datetime (e.g., 2026-02-17T14:30:45.123Z)
• timezone: The requested timezone identifier
• offset: UTC offset in hours (e.g., -5)

Convert Datetime Between Timezones

Convert a specific datetime from one timezone to another.

Pricing: $0.005

    "fromTimezone": "America/New_York",
    "toTimezone": "Asia/Tokyo"
  }
}

Request body fields:

• datetime (required): Date and time to convert (ISO 8601 format or YYYY-MM-DDTHH:mm:ss)
• fromTimezone (required): Source IANA timezone identifier
• toTimezone (required): Target IANA timezone identifier

Response fields:

Pricing: $0.005

{
  "method": "GET",
  "url": "https://pay.polymerlabs.org/proxy/https/mavs-agent-army.fly.dev/api/chronos/api/timezones?region=America&limit=50",
  "headers": {
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

Parameters:

• region (optional): Filter by region prefix (e.g., America, Europe, Asia, Pacific)
• limit (optional): Maximum number of results to return (default: 50, max: 500)

Response: Array of timezone objects with name and region fields

Health Check (Free)

Verify service availability before spending credits.

Pricing: $0.00

{
  "method": "GET",
  "url": "https://pay.polymerlabs.org/proxy/https/mavs-agent-army.fly.dev/api/chronos/api/health",
  "headers": {
    "x-polymer-pay-api-key": "{{POLYMER_PAY_API_KEY}}"
  }
}

When to Use

• User asks "what time is it" or requests current time in a specific location
• Converting meeting times across multiple timezones
• Scheduling events that span different timezones
• Finding valid IANA timezone identifiers for other API calls
• Validating timezone strings before using them in datetime operations

Best Practices

1. Always check health first before expensive operations when possible
2. Cache timezone lists – Timezone data changes infrequently; store locally to save costs
3. Use standard IANA identifiers – Always use full identifiers like America/New_York not abbreviations like EST
4. Include full datetime – For conversions, provide complete datetime strings to avoid ambiguity
5. Filter timezone queries – Use region parameter to narrow results instead of fetching all timezones
6. Handle DST transitions – Be aware that some timezones observe daylight saving time; conversions handle this automatically
7. For errors — See @skills/polymer-pay-api-errors/SKILL.md for complete error code reference and troubleshooting
