Encrypted time service
We operate authenticated time servers to ensure your systems stay synchronized and secure.
- Free: This public service can be used free of charge.
- Authenticated: Supports Network Time Security (NTS) to prevent spoofing and man-in-the-middle attacks.
- Precision: Stratum 2 servers synced to atomic-clock-backed Stratum 1 sources for millisecond accuracy.
- Privacy Protection: We do not log client IP addresses or tracking metadata from timing requests.
For reliability and accuracy, we recommend using a few different independent time sources, including the listed time servers below.
