Charger’s clock‑based features (schedules, logs) drift in time even though power is not lost.

Safety first: No special electrical risk, but configuration changes should be done carefully.

• Step 1 – Enable NTP: If the charger is network‑connected, enable automatic time synchronization with a reliable NTP server.
• Step 2 – Correct time zone: Set the correct time zone and daylight saving rules in the configuration.
• Step 3 – Manual correction: Periodically correct the time manually if network sync is not available.
• Step 4 – Firmware update: Install the latest firmware if timekeeping issues are known and fixed.
• When to call a technician: Severe drift (minutes per day) may indicate a faulty RTC oscillator and require PCB replacement.
