Time signal service

Time Signal Service is a Talking Clock Chrome extension that continuously reads out the current time and offers a full-screen digital clock with seconds, resizable widget, alarms, sleep timer, and NTP time correction. Use the clock mode to start continuous time announcements (treated as a music player so announcements continue after app closure), or switch to timer mode for voice-guided countdowns and reminder cues. The timer announces remaining intervals (5, 3, 2, 1 minutes; 30, 20, 10 seconds; and a 10→0 second countdown) and supports numeric input or history selection.

The extension also includes a Pomodoro focus timer with editable lists, automatic cycle options, and voice alerts. A professional version (trial via ads) unlocks customizable date displays, fixed themes and orientation, advanced widget customization, and Japanese calendar/era notation. Multiple high-quality voices are supported (English and Japanese), and NTP sync keeps displays and alarms accurate without changing the device clock.
