Enter the beginning year of a range of years to which this time zone definition applies. In some countries, the implementation of time zones varies from year to year. Using start and end dates enables you to set up multiple records that apply to different periods.

Enter the ending year of a range of years to which this time zone definition applies. In some countries, the implementation of time zones varies from year to year. Using start and end dates enables you to set up multiple records that apply to different periods. If you do not know when the current definition will cease to be effective, use a number such as 9999 for the end year.

Enter the actual offset in hours and minutes from Greenwich Mean Time (GMT). This number must be entered with either a plus sign (+) or minus sign (-) indicating the direction of the offset.

GMT is used internationally as the basis for establishing relationships among time zones and is never affected by daylight saving time adjustments.

When Automatically Adjust Clock for Daylight Saving is Yes, enter the first day of the week in which the change of time occurs in MM/DD format. This format is required regardless of the date format you are using.

For the United States, daylight savings normally begins on the second Sunday in March (identified by a start date of 03/08) and ends on the first Sunday in November (identified by a start date of 11/01).

This field is used in conjunction with the Weekday and Time fields to identify precisely when the time change occurs.

When Automatically Adjust Clock for Daylight Saving is Yes, enter a number (0-7) indicating the day of the week (identified by the Start Period field) when the time change occurs:

Enter 0 if the change occurs on the date entered for Start date, regardless of the day of the week on which it fails.

Enter a number in the range 1-7 corresponding to Sunday through Saturday if the change always occurs on a certain day of the week. For example, in the US, time changes always occur on Sunday (1).

When Automatically Adjust Clock for Daylight Saving is Yes, enter the exact time of day (identified by the Start Period and Weekday fields) when the time change occurs. Use 24-hour clock format. This time is always entered in standard time.

In the United States, enter 02.00 when switching from standard time to daylight savings, but 01.00 when switching from daylight savings time back to standard.
