Frequently Asked Questions

What timezone is used by default?

The Timestamp Converter uses UTC by default but can display results in your local timezone.

Can I convert timestamps from different programming languages?

Yes, the tool supports Unix timestamps (seconds and milliseconds), ISO 8601, and various date string formats.

Does daylight saving time affect the result?

Timezone conversions apply the daylight saving rules of the selected region. If you need a fixed offset, pick a UTC offset zone instead of a named city.

What is the difference between Unix seconds and milliseconds?

Seconds-based Unix time has 10 digits (typical for servers and databases); milliseconds has 13 digits (typical for JavaScript Date). The converter auto-detects the unit and lets you override it.
