+## Resolving Time Sync Issues in Prometheus
+
+If you see the following warning in Prometheus, it indicates a time sync issue.
+
+**Warning: Error fetching server time: Detected xxx.xxx seconds time difference between your browser and the server.**
+
+You can following the below steps to synchronize system time using NTP.
+
+1. **Install systemd-timesyncd** if not already installed:
+
+   ```bash
+   sudo apt install systemd-timesyncd
+   ```
+
+2. **Check service status**:
+
+   ```bash
+   systemctl status systemd-timesyncd
+   ```
+
+3. **Configure an NTP server** (if behind a corporate proxy):
+
+   ```bash
+   sudo nano /etc/systemd/timesyncd.conf
+   ```
+
+   Add:
+
+   ```ini
+   [Time]
+   NTP=corp.intel.com
+   ```
+
+   Replace `corp.intel.com` with a different ntp server that is supported on your network.
+
+4. **Restart the service**:
+
+   ```bash
+   sudo systemctl restart systemd-timesyncd
+   ```
+
+5. **Verify the status**:
+
+   ```bash
+   systemctl status systemd-timesyncd
+   ```
+
+This should resolve the time discrepancy in Prometheus.
