Terms of
reasonable use.

The site is provided for personal and professional reference. You may use it freely—to read the time, convert timezones, plan meetings, or check city data. No registration is required and no commercial restrictions apply to ordinary browsing.

We display sub-millisecond resolution but the effective ceiling is ~100 microseconds, enforced by browser security mitigations against side-channel attacks. The clock is calibrated against your device's local system time. We make no warranty that this is suitable for any specific purpose, particularly safety-critical, legal, financial, or scientific timekeeping.

City pages, timezone offsets, business hours and sun calculations are best-effort approximations. The IANA timezone database is the authoritative source for offsets and DST; we update against it regularly but cannot guarantee real-time accuracy for political or regulatory changes.

To the maximum extent permitted by law, RealTime123 and its operator, Cryptosam LLC, disclaim liability for any loss arising from reliance on the site's data, including but not limited to missed meetings, incorrect scheduling, or business interruption.

The site is provided “as is” without warranty of any kind, express or implied, including fitness for a particular purpose.

These terms and any disputes arising under them are governed by the laws of the State of Florida, United States, without regard to conflict-of-law principles. The operator's registered address is below.

The site's text, design and code are © Cryptosam LLC. City descriptions and editorial copy may not be republished without permission. Open data sources (IANA tz database, NOAA solar equations) are used under their respective public licenses. Weather conditions are provided by Apple Weather and subject to the attribution requirements shown on each city page.

These terms may change. The date at the top of this page reflects the last revision. Continued use of the site after changes constitutes acceptance.
