Time Station Emulator

Summary

Time Station Emulator Overview Time Station Emulator turns almost any phone or tablet into a low-frequency radio transmitter broadcasting a time signal that can synchronize most radio-controlled (“atomic”) clocks and watches. Real time signal broadcasts are limited in geographic range and notoriously prone to interference in urban areas, so many such clocks end up never actually using their self-setting functionality. Time Station Emulator may allow setting such clocks when/where a suitable signal is not otherwise available. Features Compatible with most radio-controlled clocks : Emulates the five operational radio time signal stations (🇨🇳 BPC, 🇩🇪 DCF77, 🇯🇵 JJY, 🇬🇧 MSF, and 🇺🇸 WWVB). : Emulates the five operational radio time signal stations (🇨🇳 BPC, 🇩🇪 DCF77, 🇯🇵 JJY, 🇬🇧 MSF, and 🇺🇸 WWVB). Network time : Derives the current time from the network using an NTP-like algorithm. : Derives the current time from the network using an NTP-like algorithm. Location-agnostic : Supports applying an offset to the transmitted time of ±24 hours from the present. : Supports applying an offset to the transmitted time of ±24 hours from the present. BST/CEST/DST-aware : Transmits daylight saving time information for DCF77, MSF, and WWVB. : Transmits daylight saving time information for DCF77, MSF, and WWVB. Leap second-aware : Transmits a DUT1 offset for MSF and WWVB. : Transmits a DUT1 offset for MSF and WWVB. Client-side, browser-based: Runs entirely in the browser; no installation, no signup, no data collection. Requirements The hard requirements of note are browser WebAssembly support and DAC support for ≥44.1 KHz PCM. Almost any device running a browser from ≥2019 should work. However, as of early 2024, Safari on iOS and Firefox on Android have multiple breaking issues and will not work. For other devices, Time Station Emulator works best with a built-in speaker of a phone or tablet. See Technical Details for an explanation. Usage Time Station Emulator is hosted at https://timesta...
