Time Keeper

By NNathan Tech

Clocks, timers, alarms, astronomy information, and time announcements in one desktop application.

Getting started

  1. Open Time Keeper.exe.
  2. The program opens on the Overview screen.
  3. Use the navigation list to move between the five main screens.
  4. Your settings, clocks, alarms, timers, stopwatch state, laps, and snoozed alarms are saved automatically.
Only one copy of Time Keeper can run at a time. If it is already running in the system tray, opening the EXE again will not create a second copy.

Overview

Clock cards

Each clock card shows the current time for one configured location. The clock graphic selected in Settings is used for all cards.

What’s next

This area shows the current local time, the next enabled alarm, the next running timer, and whether interval signals are enabled.

Astronomy

The astronomy area can show dawn, sunrise, solar noon, sunset, dusk, moonrise, moonset, and moon phase information for the selected location.

When an alarm rings

Settings

Interval signals

Enable a short signal at a chosen interval in minutes. Signals can be aligned with clock minutes.

Chimes and ticking

Select a chime style, enable clock ticking, or enable the satellite radio sound before the top of the hour.

Quiet hours

Quiet hours suppress scheduled sounds during the selected period. Enter the start and end in HH:MM format.

Time and appearance

Volume

The App volume slider controls sounds played by Time Keeper.

Reminder sound

Select the reminder sound used for alarms and completed timers. Use Refresh sounds after adding new reminder sounds to the program’s sound folder.

Global speak-time hotkey

You can configure a system-wide shortcut that speaks the current time while another application is active.

  1. Enable the global hotkey.
  2. Select one or more modifiers: Control, Alt, or Shift.
  3. Select the main key.
  4. Save the settings.
If another application already uses the chosen shortcut, Time Keeper may be unable to register it. Choose another combination and save again.

Snooze duration

Choose how many minutes an alarm waits before ringing again after Snooze is selected.

Minimize to system tray

When enabled, closing the main window hides it instead of exiting the program.

Astronomy location

Select the city used for sunrise, sunset, moon, and related information.

System tray

Time Keeper places a small clock icon in the Windows notification area. It shows the current hour and minute and updates once per minute.

Windows 11 hidden icons

Windows may place Time Keeper under the hidden-icons arrow. You can allow it to remain visible in Windows taskbar settings.

Troubleshooting

The main window disappeared after I closed it

Time Keeper may be minimized to the system tray. Open the Windows notification area and choose Show Time Keeper.

The tray icon is not visible

Check the Windows 11 hidden-icons area and taskbar system-tray settings. If the program is running but cannot be restored, close it through Task Manager and then open the EXE again.

Opening the EXE appears to do nothing

Another copy may already be running in the system tray. Time Keeper prevents multiple copies from running.

A global hotkey does not work

The shortcut may already be used by Windows or another application. Choose a different combination.

An alarm or timer makes no sound

Check App volume, quiet hours, the selected reminder sound, and the Windows output-device volume.

Astronomy information is unavailable

Select a valid astronomy city. Some moonrise or moonset events may genuinely be unavailable for a particular date and location.

The local time is wrong

Check the Windows date, time, time zone, and daylight-saving settings. Time Keeper uses the system clock.
