Log Timestamp Normalizer
When you're debugging across multiple services, log timestamps often come in different formats — ISO 8601 from one service, Unix epoch from another, syslog format from a third. This tool scans every line, detects the timestamp format, and normalizes them all to a single consistent format.

What it does
- ▸Detects and parses ISO 8601, Unix epoch (seconds and milliseconds), syslog, and Kubernetes timestamps
- ▸Normalizes all detected timestamps to a single target format you choose
- ▸Preserves the rest of each log line unchanged
- ▸Handles mixed formats within the same log stream
- ▸Reports lines where no timestamp was found
Use cases
- ▸Normalizing logs from multiple microservices before grepping or filtering
- ▸Preparing log data for import into a spreadsheet or analysis tool
- ▸Cleaning up Kubernetes pod logs that mix ISO and Unix timestamps
- ▸Standardizing syslog output for a compliance audit
How it works
Paste your log lines into the input pane
Select the target timestamp format (ISO 8601, Unix seconds, Unix millis, etc.)
The tool scans each line, detects the timestamp, and converts it

Frequently asked questions
1What timestamp formats does it detect?
ISO 8601 (2024-01-15T10:30:00Z and variants), Unix epoch seconds (1705312200), Unix milliseconds (1705312200000), syslog (Jan 15 10:30:00), Kubernetes (2024-01-15T10:30:00.123456789Z), and common variations of these.
2What happens to lines without a timestamp?
Lines where no timestamp is detected are passed through unchanged. The tool reports how many lines had no detectable timestamp so you can review them manually.
3Can I use this in a pipeline?
Yes. Chain it after a log filter or before a line sort to get chronologically ordered logs with consistent timestamps across all entries.
