Fixing Common GCS TrayClock Errors and Display Issues The Ground Control Station (GCS) TrayClock is a vital component for operators who rely on precise, real-time telemetry syncing during missions. When the TrayClock freezes, displays incorrect timestamps, or disappears entirely, it can disrupt your situational awareness.
Here is how to quickly diagnose and resolve the most common GCS TrayClock errors. 🛑 Fix 1: Restart the GCS Clock Service
Most display freezes happen because the background time-syncing service stalls. Open your system’s Task Manager or process monitor.
Locate the process named gcs_trayclock.exe or gcs_time_sync. Click End Task. Navigate to your GCS installation folder.
Double-click the executable to manually restart the service. ⏱️ Fix 2: Resolve NTP Server Desynchronization
If your TrayClock shows a different time than your actual local time, your Network Time Protocol (NTP) sync is likely broken. Open your GCS Connections Settings. Locate the Time Synchronization / NTP tab.
Verify the IP address of your master clock or telemetry source. Click Ping to check for packet loss.
Select Force Resync to align the GCS clock with the system hardware clock. 🖼️ Fix 3: Repair Missing UI Elements and Font Scaling
High-DPI displays often cause the TrayClock to disappear or render as unreadable, tiny text.
Right-click your GCS desktop shortcut and select Properties. Go to the Compatibility tab. Click Change high DPI settings. Check the box for Override high DPI scaling behavior.
Set the drop-down menu to System (Enhanced) and apply changes. 📁 Fix 4: Clear Corrupted Cache Files
Persistent configuration errors are usually caused by a corrupted local cache folder. Close the GCS application entirely. Press Win + R, type %appdata%, and hit Enter. Locate the folder corresponding to your GCS Provider. Find the subfolder named /TrayClock or /Config.
Delete the config.ini or temporary cache files inside, then restart the GCS to regenerate them.
