UnixTime
A Unix time utility for converting timestamps, counting down to events, and analyzing time ranges. Features millisecond detection, ISO 8601 output, and detailed duration breakdowns.
Commands
| Command | Description |
|---------|-------------|
| unixtime current | Show current Unix timestamp with epoch (s/ms), local, UTC, ISO 8601, day-of-year, week number |
| unixtime to-date | Convert a Unix timestamp to readable date (auto-detects milliseconds for 13+ digit values) |
| unixtime to-epoch | Convert a human-readable date string to Unix epoch |
| unixtime countdown | Show time remaining until a future timestamp (or how long ago it passed) |
| unixtime ranges | Show full duration between two timestamps (seconds through weeks) |
| unixtime version | Show version |
| unixtime help | Show available commands and usage |
Requirements
set -euo pipefail)date, awk β standard Unix utilitiespython3 (optional, for millisecond epoch)When to Use
1. Quick timestamp check β unixtime current gives epoch, local, UTC, ISO 8601, and calendar info
2. Parsing log timestamps β unixtime to-date 1700000000 or even unixtime to-date 1700000000000 (auto-detects ms)
3. Date string conversion β unixtime to-epoch '2025-06-15 14:00:00' for quick epoch lookup
4. Event countdowns β unixtime countdown shows remaining time in a breakdown
5. Duration analysis β unixtime ranges shows the gap in seconds, minutes, hours, days, and weeks
