# Swiss Railway Clock Widget
|
|
|
|
## Overview
|
|
An analog clock widget inspired by the iconic Swiss railway clock (Hans Hilfiker design).
|
|
|
|
## Core Functionality
|
|
|
|
### Time Display
|
|
- Analog clock face with hour, minute, and second hands
|
|
- Second hand sweeps smoothly in small increments (10 updates/second)
|
|
- Distinctive "pause and jump" behavior: second hand pauses at 12 o'clock for ~1.5 seconds before jumping to the next minute
|
|
- Hour and minute hands update continuously based on current time
|
|
- Clean white face with simple black hour markers
|
|
|
|
### Swiss Clock Behavior
|
|
- Second hand: smooth sweep with characteristic pause at top
|
|
- During pause: hour and minute hands continue to move
|
|
- After pause: second hand jumps to correct position and resumes sweep
|
|
- Mimics the synchronization behavior of Swiss railway station clocks
|
|
|
|
### Visual Design
|
|
- Circular white clock face
|
|
- Black outline circle
|
|
- Simple black tick marks at hour positions
|
|
- Red lollipop-style second hand (round tip)
|
|
- Black tapered hour and minute hands
|
|
- Centered on widget canvas
|
|
|
|
## Default Dimensions
|
|
- Width: 300px
|
|
- Height: 300px
|
|
- Not resizable (maintains aspect ratio)
|
|
|
|
## Technical Requirements
|
|
- Uses HTML5 canvas for rendering
|
|
- Updates 10 times per second for smooth animation
|
|
- Properly implements Swiss railway clock timing behavior
|
|
- Cleans up animation loop when widget closes
