Log Timestamp Parser & Sorter – ISO-8601, Unix, Apache/Nginx, Syslog

What Does This Tool Do?

Working with logs from different systems can be a headache when each one uses a different timestamp format. This tool takes the pain out of log analysis by automatically recognizing various timestamp formats, letting you sort entries chronologically, and converting everything to your preferred format.

Whether you're debugging a distributed system, analyzing server logs, or just trying to make sense of timestamps from multiple sources, this converter handles the heavy lifting so you can focus on what the logs actually tell you.

Key Features

• Smart Format Detection: The tool automatically figures out what timestamp format each line uses - no need to specify it manually
• Multiple Format Support: Handles ISO-8601 (including offsets and nanoseconds), Unix timestamps, RFC 2822, Apache/Nginx access and error logs, syslog, Java/Python, Go, HAProxy, and common application logs
• Flexible Sorting: Arrange your logs from oldest to newest or newest to oldest with a single click
• Batch Conversion: Transform all timestamps to a consistent format - great for comparing logs from different sources
• Custom Patterns: Use regex for input matching and strftime patterns for output formatting when you need something specific
• Preserves Context: Everything around your timestamps stays intact - log levels, messages, metadata all remain in place

Supported Timestamp Formats

Common Use Cases

Quick Start Guide

1. Paste your logs into the input area. Each line should contain at least one timestamp.
2. Check the detection results to see which formats were found and if any lines couldn't be parsed.
3. Choose your output format from the dropdown - ISO-8601 is a safe default for most use cases.
4. Apply sorting if you need logs in chronological order.
5. Click the output area to copy the converted logs to your clipboard.

Advanced: Custom Formats

For non-standard timestamp formats, you can specify custom patterns:

Input (Regex Pattern)

Use a regular expression to find the timestamp. If the pattern has a capture group, that group is parsed; otherwise the whole match is used.

Output (strftime Pattern)

Use strftime specifiers to format the output exactly how you need it.
