This C program calculates Swatch Internet Time, a revolutionary concept that could have changed how people measure time. <insert sarcasm flag here> In this alternate reality where Internet Time became the global standard, this tool would be essential for daily time management!

Internet Time divides the day into 1000 ‘beats’, abolishing time zones and providing a universal time for everyone.

• Real-time Beat Calculation: Current beat (@) based on Internet Time
• Advanced Time Conversion: Convert beats back to standard time
• Multiple Output Formats: Customizable display formats
• Timezone Support: Handle different timezone offsets (-12 to +14 hours)
• Watch Mode: Continuous real-time updates
• Verbose Mode: Detailed time information and context
• Internet Date Display: Show dates in Internet Time format
• Local Time Support: Use system local time instead of UTC
• Portable & Lightweight: Minimal dependencies, runs everywhere
• Perfect Integration: Works seamlessly with tmux, status bars, and scripts

• C compiler (GCC, Clang, or similar)
• Make (optional, for easier building)

git clone <repository-url>
cd internet_time
make

make debug

make install         # Install to /usr/local/bin (requires sudo)
# or
PREFIX=$HOME/.local make install  # Install to user directory

# Current Internet Time
./internet_time
# Output: @347.22

# With timezone offset (+3 hours)
./internet_time -t 3
# Output: @472.45

# Using local time
./internet_time -l
# Output: @123.78

# Convert beats to standard time
./internet_time -b 500
# Output: @500.00 = 12:00:00 BMT (Biel Mean Time)

# Verbose output with details
./internet_time -v
# Output: Detailed time breakdown with context

# Show Internet date
./internet_time -d
# Output: Internet Date: 2024.215 (Year 2024, Day 215)

# Watch mode (updates every second)
./internet_time -w
# Output: Continuous real-time updates

# Custom format (zero-padded integer)
./internet_time -f '@%04.0f'
# Output: @0347

# Status bar integration
./internet_time -f '%04.0f'  # Clean format for bars

# Time zone conversion
./internet_time -t -5        # Eastern Standard Time
./internet_time -t 9         # Japan Standard Time

# Business meeting scheduler
./internet_time -v           # Get full context for scheduling

• %f – Float beats (e.g., 347.22)
• %d – Integer beats (e.g., 347)
• %3d – Padded integer beats (e.g., 347)
• %04d – Zero-padded integer beats (e.g., 0347)

Add to your .tmux.conf:

set-option -ag status-right ' #[fg=cyan,bg=default]@#(internet_time -f "%.0f")'

Add to your .bashrc:

export PS1='[\u@\h \W @$(internet_time -f "%.0f")] \$ '

#!/bin/bash
current_beat=$(internet_time -f "%.0f")
if [ $current_beat -lt 500 ]; then
    echo "Good morning! It's @$current_beat"
else
    echo "Good evening! It's @$current_beat"
fi

In this alternate reality where Internet Time became the global standard:

• No Time Zones: Universal time for all
• 1000 Beats per Day: Each beat = 1 minute 26.4 seconds
• BMT Reference: Biel Mean Time (UTC+1) as the base
• Beat Periods:
  • 0-249: Morning beats
  • 250-499: Afternoon beats
  • 500-749: Evening beats
  • 750-999: Night beats
