本文详细介绍了PeopleCode中的AddToDate函数，该函数用于调整日期，包括向前或向后增加年、月、日。同时，文章还提到了两个相关函数：AddToTime用于添加小时、分钟和秒到时间；AddToDateTime则同时作用于日期和时间，处理更复杂的日期时间调整需求。

AddToDate is a PeopleCode built-in function for manipulating a date in PeopleCode.

You can use it to adjust dates forwards and backwards, by a given number of years, months or days.

The basic syntax is:

  Local date &dtExample;&dtExample = %Date;/* Get date forward 1 year, 0 months, 0 days */&dtExample = AddToDate(&dtExample, 1, 0, 0);/* Get date forward 0 years, 0 months, 30 days */&dtExample = AddToDate(&dtExample, 0, 0, 30);/* Get date backward 0 years, 3 months, 0 days */&dtExample = AddToDate(&dtExample, 0, - 3, 0);/* Get date backward 0 years, 0 months, 14 days */&dtExample = AddToDate(&dtExample, 0, 0, - 14);
 

There are are also two related functions:

AddToTime which adds, hours, minutes, and seconds to a time
AddToDateTime which works on both dates and times. This caters for 6 parameters: years, months, days, hours, minutes, and seconds.
