How To Set Date And Time Manually On Your iPhone And iPad
iPhone’s and iPad’s set their time automatically with the help of the Location Service, the Internet connectivity and carrier info. Why would you need to manually tweak the time and date? Well, the December 2 date bug, was temporarily fixable today by setting the time back on your iPhone and iPad to a date prior to December 2, 2017, at least until Apple rushed out iOS 11.2 with a permanent fix!
5 Steps To Manually Set The Time & Date On iPhone / iPad
1. Open the Settings app and tap on General.
2. Scroll and tap on Date & Time.
3. Disable the Set Automatically option.
4. Tap on the current Date and Time displayed in blue.
5. Use the vertical scrolls to adjust the data as desired.
Fact: Be aware that a wrong date and time will spoil your Calendar entries, Messages apps, some Games and even Face ID on the iPhone X will require you to reboot the device when it detects a wrong date. Use a bad date only in extreme cases like the one described above! Do upgrade to iOS 11.2 to avoid any other iPhone restarts and use your notifications and time & date settings in normal parameters!
