TID clock (and other watchfaces for pebble)#

Use rebbletool to build and install on your Pebble or in an emulator on a modern computer.

Overview#

TID clock is a Pebble watchface that displays:

• The IATA code and airport name whose local time is closest to noon.
• The current time in decimal format (TID).
• Internet time (.beats).

Prerequisites#

• A Pebble watch or a compatible emulator (e.g., Basalt).
• Rebbletool installed and configured.
• Python 3 (for timezone data generation).

For Python#

Create a virtual environment (using uv) and install dependencies:

uv venv
source .venv/bin/activate
uv pip install -r requirements.txt

Build & Installation#

Use the included run.sh helper script to streamline common tasks:

# 1) Generate timezone and airport data
./run.sh generate

# 2) Build the project
./run.sh build

# 3) Install onto the emulator (Basalt)
./run.sh install

# 4) Build and install in one step
./run.sh debug

Or run each step manually:

# Generate the airport timezone list
python3 generate_airport_tz_list.py --top 10 --max-bucket 10 --out src/c/airport_tz_list.c

# Build using Rebbletool
rebble build

# Install to device or emulator
rebble install --emulator basalt
