Creating successful software for worldwide use requires attention to locale details ranging from date and time to numeric formatting. |

| Many countries, and even some states and provinces, specify that their local time be adjusted forward or backward by one hour, to accommodate annual changes in the number of daylight hours. This may be accompanied by a change in the local name for the time zone. For example, in Toronto, Canada 1 p.m. is referred to as 1 p.m. EST (Eastern Standard Time) in the winter, and 1 p.m. EDT (Eastern Daylight Time) in the summer. Daylight Saving Time is also known as Advanced Time, Summer Time, or Legal Time (with Standard Time also known as Winter Time) in certain countries.
When a country or region changes over to Daylight Saving Time varies, and even these rules can change. For instance, in 2007 most of North America changes over to Daylight Saving Time the second Sunday in March and returns to Standard Time the first Sunday in November. The changeover to European Summer Time occurs on the last Sunday in March and they change back the last Sunday in October. This has been a common observance since 1996. |
