SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires mcp__datetime__get_current_time, mcp__datetime__convert_timezone, mcp__datetime__calculate_duration.

What problem does it solve?

Automatically detect and normalize time/date mentions in user messages, converting them into multiple timezones for clear scheduling and coordination.

Core Features & Use Cases

  • Detection & mapping: recognizes explicit timezone mentions and infers dates when present.
  • MCP integration: uses get_current_time, convert_timezone, and calculate_duration tools for robust results.
  • Use Case: "What time is 3 PM EST in Tokyo?" yields equivalent times across CET, JST, and UTC.

Quick Start

Provide a time and target timezone; the skill computes and returns multi-timezone representations.

Frequently Asked Questions about time-formatter

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I convert a time across multiple timezones automatically?

Time-formatter detects time mentions in your message and converts them across multiple timezones instantly. Provide a time and reference timezone; it outputs equivalent times in other zones plus UTC and ISO formats, handling daylight saving time automatically.

Can I use timezone conversion to coordinate scheduling across locations?

Yes. The skill recognizes scheduling requests and timezone questions, converting times across locations for clear coordination. It infers dates when present and maps common timezone abbreviations to their UTC offsets.

What's the best way to parse and normalize date and time mentions?

Timezone conversion paired with detection normalizes dates and times from natural language. The skill identifies explicit timezone references, infers missing dates, and outputs both human-readable and machine-parseable ISO formats in one pass.

Does timezone conversion handle daylight saving time transitions?

Yes. The skill handles DST-aware conversions using MCP datetime tools. It computes accurate offsets across zones regardless of whether daylight saving is active, ensuring scheduling remains correct across seasonal transitions.

Can I calculate time durations across different timezones?

Yes. Beyond conversion, the skill calculates duration between times using the calculate_duration MCP tool. This lets you determine elapsed time, meeting lengths, or project timelines while accounting for timezone boundaries.

Does this work offline with instant responses?

Yes. The skill operates offline with instant responses by integrating MCP datetime tools locally. No external API calls are required; timezone mapping and conversions execute immediately on your system.
