What is Sharp World Clock?
Sharp World Clock is a free (with a paid Professional edition) Windows application that displays the current time for cities and time zones around the world. It places clocks on your desktop, in the taskbar, or in a floating window, and includes features like world maps, alarms, meeting planner tools, daylight saving adjustments, and geolocation support. The program is designed to be lightweight, highly configurable, and suitable for both casual users and professionals who need accurate cross‑timezone awareness.

Installation and first run
- Download the installer from the official Sharp World Clock website. (For safety, always use the developer’s site or a trusted distribution.)
- Run the installer and follow on‑screen prompts. Choose the installation folder if desired.
- Launch Sharp World Clock. On first run, you’ll see a default set of clocks (often including UTC and your local time).
- Right‑click a clock or use the main menu to add new cities, change clock types, or open settings.
Adding and organizing clocks
- To add a clock: open the program menu → Add City/Time Zone → search for a city or choose a zone. Click add.
- Arrange clocks by dragging them on the desktop or using the arrangement options in the settings.
- Group related clocks (e.g., “Clients,” “Development,” “Family”) using named lists so you can switch visible sets quickly.
- Use the taskbar mode to condense many clocks into a compact, always‑available view.
Customization tips
- Pick analog clocks for a quick visual sense of day/night; use digital for precise scheduling.
- Use different colors or backgrounds to mark priority locations (red for primary office, green for teammates).
- Adjust font size so distant time zones remain readable on high‑DPI displays.
- Enable transparency and click‑through mode for clocks you want visible but non‑interactive.
- Configure alarms to trigger in the relevant time zone to avoid confusion when scheduling events.
Using the meeting planner
The meeting planner visualizes multiple locations and business hours. To use it effectively:
- Add the participant cities.
- Set preferred working hours for each location (e.g., 9:00–17:00).
- The planner highlights overlapping windows where all participants are within their business hours, simplifying time selection.
- Combine this with the calendar/alarms feature to create reminders at the chosen time in the appropriate zone.
Performance and system integration
Sharp World Clock is designed to be unobtrusive. It runs quietly in the background, with low memory usage and minimal CPU impact. It integrates with Windows time services and respects system time changes and DST transitions. The taskbar integration provides quick access without cluttering the desktop.
Pros and cons

Alternatives to consider
- World Clock apps built into macOS (for Mac users).
- Browser-based tools and web widgets (e.g., timeanddate.com).
- Mobile apps like World Clock by timeanddate or built‑in phone clocks for on‑the‑go use.
- Commercial or enterprise scheduling tools with built‑in timezone coordination if you need integrated calendar support.
Security and privacy
Sharp World Clock is a desktop utility that doesn’t require cloud syncing for basic use. If you use features that import/export lists or use online location lookup, be mindful of where you store exported files. For most users, SWC operates fully offline and poses minimal privacy concerns.
Tips for power users
- Create multiple named profiles for different workflows (e.g., “Sales,” “Engineering”) and toggle them depending on current projects.
- Use the export/import feature to replicate clock setups across multiple machines.
- Combine SWC with calendar links and timezone‑aware meeting invites to reduce manual conversions.
- Keep the timezone database updated after major governmental timezone/DST changes; check the SWC site or release notes occasionally.
Conclusion
Sharp World Clock is an excellent free option for Windows users who need reliable, flexible timezone management. Its combination of low resource usage, extensive customization, and practical scheduling tools makes it a strong choice for individuals and small teams. If you need native cross‑platform support or deeper calendar integration you may consider other tools, but for a dedicated Windows world clock, Sharp World Clock remains a top pick.
