Timestamp

Overview

Generate timestamps in YYYYMMDDHHMMSS format (e.g., 20251030143215 ) using bash date command for deterministic, reliable timestamp generation.

When to Use

• Creating timestamped filenames or directories

• Adding timestamps to logs or commit messages

• Any situation requiring consistent timestamp formatting

• When deterministic bash execution is preferred over LLM-generated timestamps

Usage

Always use the bash script to generate timestamps:

bash ./skills/timestamp/scripts/generate_timestamp.sh

Examples

Timestamped filename:

timestamp=$(bash ./skills/timestamp/scripts/generate_timestamp.sh) echo "backup_${timestamp}.tar.gz"

Output: backup_20251030143215.tar.gz

Timestamped directory:

timestamp=$(bash ./skills/timestamp/scripts/generate_timestamp.sh) mkdir "logs_${timestamp}"

In file content:

timestamp=$(bash ./skills/timestamp/scripts/generate_timestamp.sh) echo "Generated at: ${timestamp}" > output.txt
