Right-click or tap on the date and time in the Windows Notification Area in the bottom right corner of the screen.
Click Adjust date/time.
Make sure your Time zone is set properly if your computer is displaying the wrong time.
To manually adjust the time, turn off the Set time automatically option and then click the Change button.

from what you describe, they system will not shutdown. So try the following:

1. Boot to safe mode (F8 at boot) and then see if the system will reboot from the safe mode.
2. Boot to the Safe Mode again, Start RUN MSCONFIG, edit the startup group, (Basically uncheck all the items in the startup tab) reboot in the normal mode then see if it shutsdown. If it shutsdown normally, then start adding items back one at a time until you identify the items that were causing the items.

On the main menu select Settings, then Time & Date.
Set Time zone updating to Manual.
Then SCROLL down i.e. drag the menu upwards (this is the bit that many don't realise.)
Then you will be able to set the time & date.

Select Menu > Settings > Date and time. Select Date and time settings to set the date and time. Select Date and time format settings to set the formats for date and time. Select Auto-update of date & time (network service) to set the phone to update the time and date automatically according to the current time zone. Hope it helped...
