# 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
