First check whether the clock value is wrong or whether the clock is correct but showing the wrong time zone: automatic date/time and automatic time-zone detection can be separate controls. To make a manual change, turn off the corresponding automatic setting first. Menu names vary by device model, software version, carrier, and region.

There is no single menu path for every television. Sony documents layouts including Device Preferences > Date & time, with alternatives depending on the platform and model. A VPN network environment can also make a TV’s displayed time differ from the location. If the path does not match your screen, use the maker’s instructions for the exact model. See Sony’s model-specific support guidance.

Why is my device showing the wrong time?
- Identify what is wrong. If the minutes and date are wrong, check automatic date/time. If the clock value seems right but the local hour is wrong, check the time zone. These may be separate controls on Android and Windows. Google and Microsoft document both settings.
- Check the connection the device relies on. Apple directs users to connect iPhone, Mac, and Apple TV to the internet for automatic settings. Samsung says Galaxy automatic time uses the mobile network.
- Check location access if the device uses it for the time zone. On iPhone, verify the Setting Time Zone system service. Android’s location-based behavior depends on the device and its settings.
- Turn off the relevant automatic option before editing manually. Manual date/time or zone fields may not appear until the matching automatic control is disabled.
- Look for restrictions or updates. On Apple devices, carrier or regional availability, Screen Time, or a corporate profile can affect the setting. If detection remains wrong, check for pending device updates as well.
- For a TV or router, match the instructions to the model. A VPN can affect a TV’s apparent local time, while router system time can affect time-based functions such as parental controls. Consult the maker’s guidance for the exact model and firmware.
Automatic or manual: which should you use?
Automatic date/time and automatic time-zone detection are convenient when the device has the network or location access it needs. They are usually the simplest choice for routine travel when they work. A manual setting gives you direct control over the value or named time zone, but you must update it yourself when circumstances change. Choose the setting that matches the problem: changing the date/time does not fix a wrong time zone, and changing the zone does not fix an inaccurate clock.
Keep the device’s clock accurate. Samsung Support warns, “Many apps and websites will not operate correctly, and you may see security warnings, if the time and date is not accurate.” Apple Support says, “Making manual adjustments to time settings in order to change app behaviour (like game timers) isn’t recommended.”
