name: locale-dates description: "Format and convert dates, times, and durations. Compute timezones, relative time, and weekday/month names in local language. Instruction-based — no exec or dependencies needed. Use when: (1) format a date or time, (2) convert timezone, (3) 'what time is it in Tokyo', (4) 'how many days until X', (5) locale-specific formatting, (6) relative time like '3 hours ago'.

Locale Dates v3.1

Install: clawhub install locale-dates

Date/time formatting and conversion. Pure instructions — no exec, no dependencies.

Language

Detect from user's message language. Default: English.

How It Works

The agent formats dates and times using its built-in knowledge. No exec calls, no scripts, no external tools.

Timezone Conversion

Use well-known UTC offsets. Common timezones:

| ID | Offset | Region | |----|:------:|--------| | UTC | +0 | Universal | | Europe/Oslo | +1/+2 | Norway, CEST winter/summer | | Europe/London | +0/+1 | UK, BST | | America/New_York | -5/-4 | US Eastern, EDT | | America/Chicago | -6/-5 | US Central, CDT | | America/Los_Angeles | -8/-7 | US Pacific, PDT | | Asia/Tokyo | +9 | Japan | | Asia/Shanghai | +8 | China | | Australia/Sydney | +10/+11 | Australia, AEDT |

Note: The agent knows the current time from session_status. Apply offsets mentally — no exec needed.

Relative Time

Compute date differences using built-in knowledge:

| User says | Agent computes | |-----------|---------------| | "3 timer siden" | Current time minus 3 hours | | "om 2 dager" | Current date plus 2 days | | "hvor lenge til 17. mai" | Days from today to 2026-05-17 | | "i forrige uke" | 7 days ago | | "nest mandag" | Next Monday's date |

Format Conversion

Convert between formats using known patterns:

| Format | Pattern | Used By | |--------|---------|---------| | ISO 8601 | YYYY-MM-DDTHH:mm:ss±HH:MM | Technical, logs, APIs | | European | DD.MM.YYYY | Norway, Germany, EU | | American | MM/DD/YYYY | United States | | UK | DD/MM/YYYY | UK, Ireland, Australia | | Japanese | YYYY年MM月DD日 | Japan |

Weekday and Month Names

Provide names in the user's language:

| Language | Monday | January | |----------|--------|---------| | Norwegian | mandag | januar | | English | Monday | January | | German | Montag | Januar | | French | lundi | janvier | | Spanish | lunes | enero | | Japanese | 月曜日 | 1月 |

Quick Commands

| User says | Action | |-----------|--------| | "hva er klokka i Tokyo" | Apply offset, format in user's locale | | "hvor mange dager til X" | Compute difference | | "formatter denne datoen" | Convert format | | "norsk dato for 2026-04-03" | Localized format |

Guidelines for Agent

1. No exec — use built-in date knowledge
2. Always specify timezone — ambiguous dates cause errors
3. Check SOUL.md/USER.md for user's preferred format
4. Match user language — "mandag 3. mars" not "Monday, March 3"
5. Use ISO 8601 per SOUL.md convention unless user requests otherwise
6. UTC vs local time — OpenClaw logs, session transcripts, and system messages use UTC timestamps internally. When presenting times to the user, ALWAYS convert to their local timezone (Europe/Oslo = UTC+1 winter / UTC+2 summer). Never show raw UTC times without noting the conversion. Rule of thumb: if you see a timestamp and the hour seems wrong, check if it's UTC and convert.

What This Skill Does NOT Do

• Does NOT use exec, shell, or any subprocess
• Does NOT modify any files
• Does NOT require Node.js, PowerShell, or any external tool
• Does NOT persist anything

Changelog

v3.1 — 2026-04-23

• Added rule #6: UTC vs local time — always convert UTC timestamps to user's local timezone when presenting to user. OpenClaw logs and session transcripts use UTC internally.
