smoothtime
NTP without the twice-yearly trauma.
Continuous linear drift compensation.
01. Why this matters
The Natural "Astro-Shift"
Nature does not execute sudden jumps. Animals naturally synchronize their internal clocks to the gradual daily shift of the sunrise.
Humans, however, force a jarring 60-minute jump on a single Sunday. This abrupt adjustment causes "social jetlag" in our bodies and wreaks havoc on digital infrastructure - causing cron jobs to skip, logs to overlap, and IoT devices to crash.
smoothtime.io brings nature's gradual "Astro-Shift" to your network. By spreading the transition across the entire season - adjusting just a fraction of a second each day - your systems stay perfectly aligned with Daylight Saving Time without ever experiencing the trauma of a sudden jump.
Zero Discontinuities
No missed server events. No duplicate database timestamps.
02. Core Architecture
Continuous Linear Drift
Our open-source mathematical model spreads the 3600-second shift smoothly across the seasons, eliminating jarring step adjustments that crash legacy services.
Works Anywhere
Compatible with any standard NTP client via UDP Port 123. No plugins, no wrappers, no nonsense.
03. How to Use
Integration is seamless. Swap your default NTP server address with ours. We recommend configuring a standard pool as a fallback.
