ts — Instant Timestamp Converter

Zero-dependency CLI tool for bidirectional epoch ↔ human-readable timestamp conversion.

Install

Option 1: curl (fastest)

curl -fsSL https://raw.githubusercontent.com/ericjoye/ts-cli/main/ts \
  -o /usr/local/bin/ts && chmod +x /usr/local/bin/ts

Option 2: pip

pip install ts-cli

Option 3: copy

cp ts /usr/local/bin/ts && chmod +x /usr/local/bin/ts

Requires Python 3.9+ (uses zoneinfo from stdlib). No pip dependencies.

Usage

ts                          # Current time: epoch (s/ms/μs) + UTC + local
ts 1718901234               # Epoch seconds → human
ts 1718901234000            # Epoch milliseconds → human (auto-detected)
ts 1718901234000000         # Epoch microseconds → human (auto-detected)
ts "2024-06-20T14:33:54Z"  # ISO 8601 → epoch
ts "2024-06-20 14:33:54"   # Human → epoch
ts now                      # Current epoch in seconds
ts 1718901234 1718902000    # Batch: multiple timestamps
cat timestamps.txt | ts --stdin  # Pipe mode
ts 1718901234 --tz America/New_York  # Convert to timezone
ts 1718901234 --local       # Convert to local timezone

Features

• Auto-detection: Distinguishes seconds (≤10 digits), milliseconds (11–13), microseconds (16+)
• Bidirectional: Epoch → human AND human → epoch
• ISO 8601: Full support for YYYY-MM-DDTHH:MM:SSZ and variants
• Timezone support: --tz IANA_NAME or --local for system timezone
• Batch mode: Multiple args or --stdin pipe
• Zero dependencies: Single Python file, stdlib only
