The original date/time variable or array of variables.
Increments the values in a date/time variable by a specified amount.
The original date/time variable or array of variables.
A date/time variable incremented by the specified amount.
If present and nonzero, excludes predefined weekends and holidays from the result. The default is no compression (0).Day
Specifies an offset value in days.Hour
Specifies an offset value in hours.Minute
Specifies an offset value in minutes.Month
Specifies an offset value in months.Second
Specifies an offset value in seconds.Year
Specifies an offset value in years.
NOTE: Only one keyword can be specified at a time. You cannot, for example, specify both years and months in a single DT_ADD call. But if you need to add, for example, one day and one hour, you can simply add 25 hours.
The keywords specify how the dates and/or times are incremented (added to). If no keyword is specified, the default increment is one day.
Only positive whole numbers (including zero) can be used with the keywords to specify an increment. Therefore, the smallest unit that can be added to dt_var is one second.
dtarray = STR_TO_DT(['17-03-92', $

dtarray1 = DT_ADD(dtarray, /Day)
DT_PRINT, dtarray1
