hour-meter

What This Skill Does

The Hour Meter skill, published under the alias TARDIS on ClawHub, is a sophisticated, tamper-evident digital tracking tool designed to log the passage of time relative to specific epochs. Functioning like a digital analog Hobbs meter, it allows users to monitor uptime, service intervals, personal milestones, or project durations with cryptographic assurance. Unlike simple timers, this skill uses a checksummed paper-code system to ensure that logs remain untampered. It operates in three distinct modes: Count Up (elapsed time since an event), Count Down (time until a future deadline), and Count Between (journey tracking between two specific dates). Its core strength lies in its verification mechanism, ensuring that if you check your meter against a saved paper code or witness file, any alteration or tampering is immediately detected.

Installation

To integrate this skill into your environment, utilize the ClawHub package manager. Run the following command in your terminal: clawhub install openclaw/skills/skills/rm289/tardis Ensure you have the necessary permissions for your local configuration directory to allow the creation of the witness file.

Use Cases

• Professional Maintenance: Tracking machinery runtime or server uptime for scheduled service intervals.
• Personal Productivity: Habit tracking, such as sobriety counters or time spent on specific deep-work projects.
• Project Management: Monitoring time remaining until critical milestones or deadlines.
• Accountability: Creating verifiable records for long-term goals that require tamper-proof historical data.

Example Prompts

1. "OpenClaw, start a new count-up meter for my home office server uptime named 'server-main' starting from yesterday at midnight."
2. "Check the status of my 'smoke-free' meter and confirm it against the paper code 318B-3229-C523-2F9C-V."
3. "Set up a count-down meter for the 'annual-review' project due on December 31st and remind me when I reach 50% of the time elapsed."

Tips & Limitations

Always store your paper code in a secure physical location; the verification process depends entirely on the accuracy of this code. If you lose the code and your witness file, you cannot verify the integrity of the meter. The SendGrid integration is optional but highly recommended for automated, reliable backups of your meter status. Be aware that the ~/.openclaw/meter-witness.txt file is append-only, so protect it from unauthorized deletion to ensure your long-term record keeping remains intact.
