3 Ways to Get Unix Timestamps in Shell: Seconds and Milliseconds

Shell scripting is ideal for automation, and getting Unix timestamps is a common task. This guide covers 3 methods to generate timestamps in seconds or milliseconds, perfect for scripts and Discord, with DevUtils’ free tool for validation.

Unix Timestamp Overview

A Unix timestamp counts seconds or milliseconds since January 1, 1970, 00:00:00 UTC. Seconds are 10 digits (e.g., 1694870400), milliseconds are 13 digits (e.g., 1694870400000) (Keywords: unix timestamp in seconds or milliseconds).

Method 1: Using date Command

• Seconds:

date +%s
# Output: 1694870400

• Milliseconds(if supported):

date +%s%3N
# Output: 1694870400000

Method 2: Using bc for Precision

For systems lacking %N:

echo "$(date +%s) * 1000 + $(date +%N)/1000000" | bc
# Output: 1694870400000

Method 3: Generating Discord Timestamps

Input Shell timestamps into DevUtils’ Timestamp Converter to create Discord formats:

• Enter 1694870400, select F, get <t:1694870400:F>。
• Paste into Discord, displays “September 16, 2023, 00:00.”
• Keywords: Unix timestamp for Discord.

Verification and Applications

DevUtils’ tool verifies Shell timestamps:

• Check dates from timestamps.
• Convert dates to timestamps (Keywords: convert date to timestamp).
• Applications include logging, automation, and Discord event scheduling.

Shell offers versatile timestamp methods, and DevUtils’ free Timestamp Tool ensures accuracy. Try it now to enhance your scripting!
