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:

IDOffsetRegionUTC+0UniversalEurope/Oslo+1/+2Norway, CEST winter/summerEurope/London+0/+1UK, BSTAmerica/New_York-5/-4US Eastern, EDTAmerica/Chicago-6/-5US Central, CDTAmerica/Los_Angeles-8/-7US Pacific, PDTAsia/Tokyo+9JapanAsia/Shanghai+8ChinaAustralia/Sydney+10/+11Australia, 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 saysAgent 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:

Weekday and Month Names#

Provide names in the user's language:

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#
