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:

Guidelines for Agent
- No exec — use built-in date knowledge
- Always specify timezone — ambiguous dates cause errors
- Check SOUL.md/USER.md for user's preferred format
- Match user language — "mandag 3. mars" not "Monday, March 3"
- Use ISO 8601 per SOUL.md convention unless user requests otherwise
- 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

- 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.
1---2name: locale-dates3description: 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'.
