How to Fix a Dash Cam That Resets the Time and Date

Why the timestamp resets

An accurate time stamp is one of the most important parts of dash cam footage. It helps you show when an incident happened and makes it easier to match video with other records, such as a repair order or an insurance claim. When the clock resets, the camera usually returns to a factory default date and time, which can make the clip look unreliable.

Most dash cams keep the clock alive with a small rechargeable battery or a supercapacitor. When you switch off the ignition, that component stores just enough power for the internal clock and settings. If it wears out or cannot hold a charge, the camera forgets the time the next time power is lost. Learn more about the tradeoff between dash cam capacitor vs battery.

Check the backup battery or capacitor

If the time resets only after the car has been off for a long time, suspect the internal backup power source. In some dash cams, the battery is replaceable by opening the casing. In others, especially capacitor models, the component is soldered and not user serviceable. If your camera has a removable battery, try a fresh one and see if the clock holds.

Signs of a weak backup component include the time resetting after every shutdown, the menu losing date settings, and the camera behaving as if it just came out of the box:

If the backup battery is swollen, do not open or charge it. See the guides on dash cam battery won't hold charge and dash cam supercapacitor failure for more on the failure modes.

• The time resets after every shutdown
• The date returns to the factory default
• The camera acts as if it has no saved settings

Enable GPS time sync

Many dash cams include GPS. The same receiver that records speed and location can also update the clock from the satellite signal. If the camera has this feature, enabling GPS time sync usually prevents the clock from drifting after a reset.

In the camera menu, look for a time setting, a GPS setting, or an option called auto time sync, GPS time, or time from GPS. It often appears only when the GPS antenna is connected and has a signal. If the camera still shows the wrong time, try moving the antenna to a place where it can see the sky. See dash cam GPS explained and how to fix dash cam GPS signal.

Some dash cams need both GPS time sync and a correct time zone. The satellite signal is based on a global standard, so the camera must convert it to your local time. Set the time zone in the menu, and turn on daylight saving time if the camera has that option. See how to set dash cam time zone.

Set the clock manually when GPS is not available

If your dash cam does not have GPS, you can set the date and time manually in the settings menu. Check the time zone setting first so the clock does not display UTC or another region's time. Some models also let you choose a 12-hour or 24-hour format.

Manual clocks will drift gradually and will reset if the camera loses power for long enough. If manual setting is your only option, make a habit of checking the timestamp every few weeks. For comparison, a dash cam with GPS can correct itself each time it locks onto satellites.

Update firmware, then try a reset

Clock bugs can sometimes be fixed by a firmware update. Dash cam makers release updates that address timekeeping, GPS acquisition, and other software issues. Check the manufacturer's support page for your model, download the correct file, and follow the instructions. See dash cam firmware update.

If the clock still resets after a firmware update and a manual time setting, consider a factory reset. Resetting clears the old settings and gives the clock a clean start. After the reset, reconfigure the time zone, GPS time sync, and any other options. If the problem returns immediately, the internal backup component is the likely cause. See how to factory reset dash cam.

What to look for when buying a dash cam

If you are shopping for a replacement, prioritize a dash cam with GPS time sync. It removes most of the manual clock work and corrects itself automatically. GPS also adds speed and route data to your footage, which can be useful after an incident. See best dash cams with GPS and best 4K dash cams with GPS.

Capacitor-powered cameras are generally a better fit for hot climates because capacitors tolerate heat better than batteries. If you plan to use parking mode, a capacitor model with reliable power management is worth considering. See best parking mode dash cams.

Questions

Why does my dash cam reset the time every time I start the car?

The internal battery or supercapacitor that preserves the clock is probably not holding a charge. When power is cut, the camera loses its time setting. Try a battery replacement if the model allows it, or enable GPS time sync if the camera has that option.

Will GPS time sync fix a resetting clock?

Usually yes. Once the dash cam locks onto GPS, the receiver can set the clock from the satellite signal. Make sure GPS time sync is enabled and the time zone is correct. If the camera still does not update, check the GPS antenna connection and signal strength. See how to fix dash cam GPS signal.

Does replacing the backup battery solve the reset?

It can, if the battery is replaceable and truly is the cause. Capacitor models often do not have user-serviceable parts. If you are not comfortable opening the camera, contact the manufacturer or a repair service. See the dash cam capacitor vs battery explainer for more context.

Why does the time drift even when the dash cam does not reset?

Manual clocks without GPS updates can drift over time, especially if the camera is in a hot or cold environment. Enable GPS time sync if your camera supports it, or make a habit of correcting the clock periodically. Firmware updates may also improve timekeeping.
