It happens to the best of us. You glance down at your wrist after a long flight or a daylight saving shift, expecting to see the exact moment of the day, but your tracker is living in the past. Or maybe the future. Either way, it’s annoying. You bought a high-end health tracker, not a random number generator. Figuring out how to adjust time on fitbit devices isn't always as intuitive as you’d hope because, honestly, there isn't a "set time" button on the watch itself.
Fitbit devices are slaves to your smartphone. They don't have internal clocks that you manually wind or digital interfaces where you type in the hour and minute. They just mirror what your phone says. If the sync breaks, the time breaks. It's a tethered relationship that works great until it doesn't.
The Sync Solution: Why Your Clock is Drifting
Most of the time, a simple sync fixes everything. If your Fitbit shows the wrong time, it’s usually because it hasn't talked to the Fitbit app in a while. Bluetooth is finicky. Sometimes the app gets killed in the background by your phone’s aggressive battery-saving settings. Open the app on your iPhone or Android.
Tug down on the main dashboard screen. You’ll see that little rotating icon at the top. Once that finish line is crossed, the time usually snaps into place. If it doesn't? Well, then we have to dig into the weeds of the time zone settings, which is where things get a bit more technical.

Changing Time Zones Manually
Sometimes the "Automatic" setting is the actual villain of the story. If you’re traveling and your phone hasn't updated its own location, or if you're near a state line where towers are bouncing signals from a different zone, your Fitbit gets confused.
You need to head into the app settings. Tap your profile picture or the "device" icon in the top left. Go to App Settings. Look for Time Zone. You'll probably see a toggle that says "Set Automatically." Switch it off. This feels counterintuitive, I know. But by switching it off, you can manually select your city or time zone. Once you pick the right one, go back to the main screen and sync again.
This is the "turn it off and back on again" of the wearable world. It forces the software to overwrite whatever cached data was lingering in the hardware.

Troubleshooting the Stubborn Tracker
What if you did the sync and the time zone dance, but your Versa 4 or Charge 6 is still stubbornly clinging to the wrong hour? This is where people start getting frustrated. I've seen forum posts on the Fitbit Community boards where users swear their device is haunted. It's not haunted; it’s likely a Bluetooth handshake issue.
- Toggle Bluetooth: Turn it off on your phone, wait ten seconds, and flip it back on.
- The Restart: Every Fitbit has a restart sequence. For a Luxe or Charge 5/6, it’s usually on the charging cable button. For a Sense or Versa, you hold the side button for about 10 seconds until the Fitbit logo pops up.
- Check the "Always Connected" toggle: In the Android app especially, there is an option to keep a persistent connection. If this is off, the sync might fail halfway through, leaving your clock stranded.
Why 12-Hour vs 24-Hour Clock Matters
Some people hate military time. Others can't live without it. If you want to change how the time looks—not just what the time is—you can't do that in the app's "Time Zone" section. You have to go to the Fitbit.com online dashboard. This is a weird quirk of the Fitbit ecosystem that they haven't quite streamlined yet.
Log in to your profile on a web browser. Click the gear icon. Go to Settings. Scroll down to Personal Info. There, you’ll find "Clock Display Time." This is where you switch between 12-hour and 24-hour formats. After you save the change on the website, you still have to go back to your phone app and sync the device. It’s a three-step process for a one-step problem, but that’s the current architecture.

The "Daylight Saving" Nightmare
Every March and November, Fitbit support centers get slammed. Technically, the device should handle the jump automatically. But if your phone is in "Low Power Mode" overnight during the switch, it might not push the update to the tracker.
If you wake up and you're an hour behind, don't panic. Don't factory reset your device. That's overkill. Just open the app, ensure your phone has the correct time, and perform a manual sync. If it still fails, use the "manual time zone" trick mentioned above to force it forward or backward, then switch it back to automatic once it catches up.
Real World Nuance: When Hardware is the Problem
Is it possible your Fitbit is just broken? Rarely, but yes. If the time is drifting by a few minutes every day—not just a solid hour—it might be an internal oscillator issue. This is extremely rare in modern wearables, but it happened more frequently with older models like the original Alta or the Flex. If you've synced five times and the watch is still losing three minutes every hour, it's time to contact support. You're likely looking at a replacement rather than a settings fix.
But honestly? 99% of the time, it's just a communication breakdown between the app and the wrist.
Actionable Steps to Fix Your Fitbit Time Right Now
If you're looking at your wrist right now and the numbers are wrong, follow this exact sequence. Don't skip steps.
- Check your phone first. If your phone clock is wrong, your Fitbit will never be right.
- Open the Fitbit app. Ensure you see "Connected" under your device image.
- Force a sync. Pull down on the dashboard.
- Check the Time Zone setting. Tap your Profile > App Settings > Time Zone. Toggle "Set Automatically" to OFF, select a random time zone, sync, then toggle it back to ON (or your correct zone) and sync again.
- Restart the tracker. Use the specific button combo for your model (usually holding the side button or the charging cable button).
- Verify on the web. If you're trying to change the 12/24 hour format, use the desktop dashboard at Fitbit.com.
Once the sync is successful, your tracker will stay accurate as long as it check-ins with your phone at least once or twice a day. To prevent this from happening again, make sure the Fitbit app is "whitelisted" in your phone's battery optimization settings so the background sync isn't killed to save a tiny bit of juice.
