World timezone converter — convert times across 200+ cities worldwide. Perfect for international calls, remote work, travel planning, and global business. Fe...
Usage Guidance
This skill appears to be what it claims: a local timezone utility with no networking or secret access. Before installing or running it: 1) note the SKILL.md examples reference 'world_timezone.py' but the included script is scripts/timezone.py — rename or call the correct file. 2) Inspect the script (you already have it) and run it in a sandbox or non-sensitive environment first; it executes the system 'date' command via subprocess, which is normal for this purpose but the flags used may fail on Linux. 3) Expect some functional issues (duplicate/ambiguous city keys, non-portable date usage, and the simple convert implementation may not produce accurate conversions in all cases). If you need production-grade accuracy, prefer a well-maintained timezone library (e.g., pytz/zoneinfo) or a tested package.
Capability Analysis
Type: OpenClaw Skill
Name: world-timezone-pro
Version: 1.1.0
The skill provides legitimate timezone conversion and world clock functionality. It uses a hardcoded mapping of cities to IANA timezones and retrieves time data by invoking the system 'date' utility via subprocess.run (scripts/timezone.py). No evidence of data exfiltration, shell injection, or malicious prompt instructions was found in SKILL.md or the Python code.
Capability Assessment
Purpose & Capability
The name/description match the included Python script (timezone lookup, conversion, city search). The code only uses local time utilities and a built-in timezone map; it does not request unrelated credentials or services.
Instruction Scope
SKILL.md shows example usage of 'world_timezone.py', but the provided script file is scripts/timezone.py (timezone.py). The runtime instructions do not tell the agent to read arbitrary files or environment variables, which is good, but the filename/path mismatch means the README examples won't run as-is without renaming or adjusting the command.
Install Mechanism
There is no install spec (instruction-only style), and the code is included as a local script. The script calls the system 'date' binary via subprocess — no remote downloads or package installs are performed by the skill itself. Note: use of specific 'date' flags (e.g., '-j', '-f') is BSD/macOS-specific and may not work on Linux.
Credentials
The skill declares no required environment variables or credentials. The script passes a minimal env={'TZ': tz_name} to subprocess.run (replacing the child environment with only TZ), which limits exposure rather than widening it.
Persistence & Privilege
always is false and the skill does not request persistent system-level privileges or modify other skills or configs. It does not write persistent data or store credentials.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install world-timezone-pro - After installation, invoke the skill by name or use
/world-timezone-pro - Provide required inputs per the skill's parameter spec and get structured output
