Best Timestamp Converter for Log Analysis (2026)

Server logs, database records, and API responses often contain Unix timestamps — seconds since January 1, 1970. Converting these to human-readable dates is essential for debugging timing issues, analyzing user behavior, and correlating events across systems.

Unix Timestamp Converter

Recommended

Bidirectional conversion between Unix timestamps and human-readable dates with millisecond support.

Best for: Converting timestamps from logs, databases, and API responses to readable dates

  • Shows current Unix timestamp
  • Bidirectional — date to timestamp and back
  • Timezone-aware display

Cons

  • Single timestamp at a time — no batch conversion

Recommended Workflow

  1. 1

    Copy the Unix timestamp from your log file or API response

  2. 2

    Paste it into the converter to see the human-readable date and time

  3. 3

    Check if the timestamp is in seconds or milliseconds (tool auto-detects)

  4. 4

    Use reverse mode to generate timestamps for date-based queries

Frequently Asked Questions

What's the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1709800400). Millisecond timestamps are 13 digits (e.g., 1709800400000). Our converter handles both automatically.

Why do logs use Unix timestamps instead of dates?
Unix timestamps are timezone-independent, easily sortable as numbers, compact, and unambiguous. They avoid date format confusion (MM/DD vs DD/MM) and timezone conversion issues.

How do I find timestamps in log files?
Look for 10-digit (seconds) or 13-digit (milliseconds) numbers. Common field names: timestamp, created_at, time, epoch, ts. In JSON logs, these are usually numeric values without quotes.
