Set the time and date manually.
If you’re having trouble connecting to a network or if you simply prefer setting the time yourself, you can change the date and time manually. When you select a time zone that uses Daylight Savings (such as EST, PST, etc.), your device will automatically change the time on the appropriate date, so you don't have to worry.
Navigate to and open Settings. Tap General management, and then tap Date and time. Make sure the switches next to Automatic date and time and Automatic time zone are turned off. When the automatic setting is disabled, options for manually changing the time will appear.
You can change the following settings:
Select time zone: Choose the appropriate region and time zone based on your location. Even though it’s set to manual, your phone will still automatically change during Daylight Savings Times, based on the zone you picked.
Set date: Select a date from the calendar, and then tap Done.
Set time: Change the time by swiping or typing, and then tap Done.
