Description
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
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install world-timezone-pro
  3. After installation, invoke the skill by name or use /world-timezone-pro
  4. Provide required inputs per the skill's parameter spec and get structured output
