You’re staring at your screen and something feels off. Maybe you’re at the airport, or perhaps you’re trying to "time travel" in a mobile game to skip a long cooldown period. Whatever the reason, you need to know how do you change time on iphone without breaking your iCloud sync or messing up your calendar. It sounds like the simplest task in the world. It isn't always.
Sometimes the button is grayed out. Sometimes the phone insists you're in Cupertino when you're clearly in Chicago. Apple makes this "automatic" by default, which is great until it isn't. If you've ever landed in a new time zone and your phone stayed stuck in the past, you know the frustration. It’s not just about the clock; it’s about your alarms, your text timestamps, and your sanity.
The basic path to changing your clock
Let's get the standard stuff out of the way first. Most people just need to toggle a single switch. You’ll want to head into your Settings app. It’s that gray gear icon you probably have tucked away in a folder somewhere. Once you’re in, tap on General and then look for Date & Time.
By default, Set Automatically is turned on. This is where your iPhone talks to local cell towers and GPS to figure out exactly where you are and what time it is. If you want to change it manually, you have to toggle that switch off.
Suddenly, a new row appears. It shows the current date and time in blue text. Tap that. Now you can scroll through the wheels to pick whatever time you want. It’s satisfying. But be careful. If you change the date to something months in the future, your phone might start screaming at you with "Security Certificate" errors when you try to use Safari. The internet relies on synchronized clocks to verify that websites are safe. If your phone thinks it's 2029, it won't trust a security certificate from 2026.
Why is the time grayed out?
This is the big one. I see this all the time. You go to the settings, and the "Set Automatically" toggle is a ghostly gray. You can't touch it. You can't change it. You feel locked out of your own device.
Usually, this is because of Screen Time restrictions.
Apple added Screen Time as a way to help people stay off their phones, but it also acts as a parental control. If you have a "Content & Privacy Restriction" active, or if your phone is managed by a workplace (MDM profiles), they often lock the time settings. Why? Because kids figured out years ago that they could bypass app limits by just changing the clock back two hours.
To fix this, go to Settings > Screen Time. If you have a passcode, you'll need it. Look for Content & Privacy Restrictions. If it's on, check the "Location Services" or just turn the whole thing off for a second. Often, simply turning off the Screen Time passcode feature entirely will unlock the date and time settings instantly.
The Time Zone glitch and how to beat it
Sometimes you've figured out how do you change time on iphone but the "Time Zone" search box just spins and spins. It can't find your city. This is almost always a Location Services hiccup. Even if you want to set the time manually, the phone needs to know its relative position to handle things like Daylight Savings correctly.
Check this specific path: Settings > Privacy & Security > Location Services > System Services.
Way down at the bottom of that list, there is a toggle for Setting Time Zone. If that’s off, your iPhone is basically blindfolded. Flip it on. Give it a minute. Suddenly, your phone will realize you aren't in the middle of the ocean and let you pick a city.

Manual vs. Automatic: The trade-offs
Honestly, 99% of the time, you should leave it on automatic. Apple uses a protocol called NTP (Network Time Protocol) which is insanely accurate. It syncs with atomic clocks. When you go manual, you’re introducing human error.
- Pro: You can set your clock five minutes fast so you're never late for meetings.
- Con: Your "Find My" tracking might get glitchy.
- Pro: You can trick games into giving you more lives.
- Con: Your emails might show up in a weird order because the "received" metadata doesn't match your local device time.
I’ve seen people miss flights because they manually set their time and forgot that the destination was on a weird half-hour offset (like parts of Australia or India). If you're traveling, the automatic setting is your best friend because it handles those weird geopolitical time shifts that we mortals can't keep track of.
Fixing the "Date & Time" sync after a restore
If you just got a new iPhone or restored from a backup, the time might be wildly wrong. This happened to my brother last week. His phone thought it was 1969. That’s the "Unix Epoch" — basically the "Year Zero" for the software your iPhone runs on.
If this happens, connect to Wi-Fi immediately. The phone needs a "heartbeat" from a server to realize what decade it is. If Wi-Fi doesn't fix it, plug it into a computer with iTunes (or Finder on Mac). The physical connection forces a handshake that usually snaps the clock back to reality.
Actionable steps for a perfect clock
If your time is wrong, follow this exact sequence to force a reset.
First, toggle Set Automatically off and then back on. It sounds dumb, like "unplug it and plug it back in," but it forces the phone to re-ping the NTP servers.
Second, if that fails, check for an iOS update. Sometimes carrier settings updates (which come bundled with iOS or as a separate popup) include fixes for how your phone talks to cell towers for time data.
Third, reset your Network Settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Warning: this will wipe your saved Wi-Fi passwords, but it clears the cache of the systems that handle GPS and time data. It’s the "nuclear option" for time issues, but it works when nothing else does.
Finally, ensure your Apple ID region matches your physical location. If you’re using a US App Store account but you’re living in Berlin, the conflict between your account's "home" and your GPS location can occasionally cause a lag in how the clock updates. Double-check your region in Settings > [Your Name] > Media & Purchases > View Account.

Correcting your iPhone's time isn't just about knowing what hour it is. It's about ensuring your encrypted data stays valid and your digital life stays in sync. Stick to the automatic settings unless you have a very specific reason to do otherwise, and always keep your Screen Time settings in check if you find yourself locked out of the menu.
