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

Bash 4+ (set -euo pipefail)
date, awk — standard Unix utilities
python3 (optional, for millisecond epoch)
No external dependencies or API keys

When to Use

Quick timestamp check — unixtime current gives epoch, local, UTC, ISO 8601, and calendar info
Parsing log timestamps — unixtime to-date 1700000000 or even unixtime to-date 1700000000000 (auto-detects ms)
Date string conversion — unixtime to-epoch '2025-06-15 14:00:00' for quick epoch lookup
Event countdowns — unixtime countdown shows remaining time in a breakdown
Duration analysis — unixtime ranges shows the gap in seconds, minutes, hours, days, and weeks

Examples

# Show current Unix time with full details
unixtime current

# Convert timestamp to date (auto-detects milliseconds)
unixtime to-date 1700000000
unixtime to-date 1700000000000

# Convert date string to epoch
unixtime to-epoch '2025-06-15 14:00:00'
unixtime to-epoch 'Jan 15 2025'

# Countdown to a future timestamp
unixtime countdown 1800000000

# Analyze a time range
unixtime ranges 1700000000 1700086400
