Keep your system time accurate, because Windows uses it to timestamp files and email, schedule tasks, and record events.
To set the date and time:
1. Choose Start > Control Panel > Date, Time, Language, and Regional Options > Date and Time, or double-click the clock in the taskbar.
2. On the Date & Time tab (Figure 4.48 ), adjust the date and time as needed.
3. On the Time Zone tab (Figure 4.49 ), select your time zone in the list.
Windows assumes that you want to Automatically Adjust Clock for Daylight Saving Changes. Uncheck this box if you don't want to use daylight saving time.
4. On the Internet Time tab (Figure 4.50 ), check Automatically Synchronize with an Internet Time Server to synchronize your computer clock with a highly accurate clock. (Type any time-server address in the Server box.) Once a week is the only interval you get unless you click Update Now.
5. Click OK (or Apply).
Tips
Internet-time synchronization occurs regularly only if you have a full-time internet connection such as DSL or cable. If you use dial-up, click Update Now while you're connected to the internet to synchronize your clock immediately.
A time server won't synchronize your system time if your date is incorrect.
