Set the time zone. When you reset the time zone, the clock will reset. This means that if you set the time before you set the time zone, it will reset and you'll have to repeat the process. By setting the time zone first, you'll save yourself some extra work.- You need to know your time zone in relation to Greenwich Mean Time (GMT). If you're in the central time zone, you're 6 hours behind GMT, so you'd indicate this via -6. For instance, you'd enter

command. For example, enter
