It happens to the best of us. You wake up, look at your nightstand, and realize your phone is showing 3:15 AM when the sun is clearly pouring through the blinds. Or maybe you just landed in a different time zone and your device is stubbornly clinging to "home" time like a homesick tourist. Honestly, learning how to set clock on my phone should be the easiest thing in the world. It’s a foundational piece of tech. But between Android’s fractured ecosystem and Apple’s penchant for hiding settings inside menus you haven't touched in years, it can get weirdly complicated.
Most people think their phone just "knows" what time it is because of some magic satellite link. Sorta. In reality, your phone is juggling signals from cellular towers, GPS satellites, and NTP (Network Time Protocol) servers. When one of those links breaks, your internal clock drifts. Or worse, it jumps.
The Android way to fix your time
If you’re rocking a Samsung, Pixel, or Motorola, the path is generally the same, though the names of the buttons might vary slightly. You’ve got to dig into the system settings. It’s usually buried under "System" or "General Management."
Start by swiping down and hitting that little gear icon. Don’t get distracted by the notifications. Once you’re in, look for Date & time. On a Google Pixel, you’ll find this under System. On a Samsung Galaxy, you’ll likely need to tap General management first.
Most of the time, the "Set time automatically" toggle is turned on. Turn it off.
Seriously.
Toggle it off, wait three seconds, and toggle it back on. This forces the phone to re-sync with the local cell tower. If that doesn't work, you're going to have to go manual. Tap on Date or Time and scroll through the wheels until you hit the right numbers. It feels a bit primitive, like winding an old watch, but it gets the job done when the network is being flaky.
What about the time zone?
Time zones are the silent killers of punctuality. If your clock is exactly one or two hours off, it’s not a "time" problem—it’s a "zone" problem. Android usually handles this via the Set time zone automatically feature. This uses your location data. If you have "Location" turned off to save battery, your phone might get confused about where you are.

Check your Location Services. If the phone can't see the GPS satellites, it might think you're still in Chicago when you're actually in Denver. Make sure "Use location to set time zone" is active if you travel a lot.
Setting the clock on an iPhone
Apple keeps things a bit more locked down. To figure out how to set clock on my phone when you’re on iOS, you need to head to the Settings app. It’s the gray one with the gears.
Tap General, then Date & Time.
You’ll see a switch labeled Set Automatically. If this is grayed out, you likely have a "Screen Time" restriction or a corporate management profile installed on your phone. Companies do this so employees can't "cheat" on time-tracking apps by changing the phone clock. If it’s not grayed out, toggle it.
If you need to change it manually:
- Turn off Set Automatically.
- Tap the blue date and time that appears below.
- Use the calendar picker and the clock dial to set the moment.
It’s worth noting that if you change your time manually to "game" a mobile app (like getting more lives in Candy Crush), you might break your browser. Websites use SSL certificates that are time-sensitive. If your phone thinks it’s 2029, Safari will refuse to load Google because the security certificate will appear "invalid" or "expired." It’s a mess.
Why your phone clock keeps resetting itself
Sometimes, you set the clock, and then an hour later, it’s wrong again. This is infuriating.

There are a few real-world reasons for this. The most common is a bad SIM card or a glitchy connection to your carrier. Your phone is constantly pinging the "Network Identity and Time Zone" (NITZ) signal from the tower. If that signal is corrupted, your phone updates to the wrong time.
Another culprit is the "Automatic" setting itself. In border towns—think places like the border of Arizona (which doesn't do Daylight Savings) and New Mexico—your phone might bounce between two different towers. One says it’s 2:00 PM, the other says 3:00 PM. Your phone ends up flickering between them like a strobe light. In these cases, the only solution is to kill the automatic setting and lock it to a specific city.
The CMOS battery myth
On old PCs, there was a tiny coin-cell battery that kept the clock running when the power was off. People often ask if phones have these. They don’t. Modern smartphones use a tiny bit of "ghost power" from the main lithium-ion battery to keep the internal real-time clock (RTC) ticking. If your battery hits 0% and stays there for weeks, even that tiny bit of juice disappears. When you finally charge the phone, it might think it’s January 1, 1970.
Unix-based systems (which include Android and iOS) measure time in seconds since the "Unix Epoch"—which is midnight on Jan 1, 1970. If your phone reverts to this date, it’s a sign your battery was completely, totally drained.
Dealing with Daylight Savings Time
Daylight Savings is the bane of tech developers. Every few years, a government changes its mind about when the clocks should shift. If your phone’s operating system isn't updated, it might use the old rules.
Keeping your phone software updated is actually a "time setting" task. Those "Security Updates" often include Time Zone Database (tzdb) updates. If you’re running Android 10 in a world that’s moved to Android 16, your phone might miss the spring forward or fall back by a week because the laws changed and your phone didn't get the memo.
Actionable steps to fix your time right now
If your clock is wrong and you need it fixed immediately, follow this checklist. Don't skip steps; the order actually matters for resetting the handshake between your phone and the network.

1. The "Toggling" Method
Go to your settings and find the Date & Time menu. Toggle the "Set Automatically" switch to OFF. Wait a beat. Toggle it back to ON. This is the tech equivalent of "unplugging it and plugging it back in."
2. Check Your Location Permissions
Ensure that your phone has permission to use your location for setting the time zone. On iPhone, this is under Privacy & Security > Location Services > System Services. Make sure Setting Time Zone is toggled green. On Android, just search "Location" in the settings search bar and ensure it's active.
3. Update Your Software
If you've been putting off that 1.2GB system update, do it now. It likely contains the latest time zone maps provided by the IANA (Internet Assigned Numbers Authority). This prevents your phone from being "that guy" who shows up an hour early to the meeting.
4. The Airplane Mode Trick
Sometimes the cellular radio gets "stuck" on a specific tower's data. Flip Airplane Mode on for 30 seconds. This kills all connections. When you flip it off, the phone is forced to do a fresh search for the nearest tower, which usually carries the most accurate local time signal.
5. Manual Override
If all else fails—maybe you're in a remote area or on a cruise ship with weird Wi-Fi—set it manually. Pick a major city in your time zone rather than letting the phone guess. This prevents the "jumping" effect when your signal gets weak.
Setting the clock is usually a "set it and forget it" situation, but when the hardware fails or the network gets confused, knowing your way around the Date & Time menu is the only way to ensure you aren't late for work. Keep that "Set Automatically" switch on for 99% of your life, but don't be afraid to take the wheel when the tech gets glitchy.
