Time Merge Variables

In a dataset, the variable types are date/time, numeric (real, integer, or double precision), or string, and variable origins are raw, independent, or computed.

Numerics and strings can be attached to a date/time variable, or they can be unattached, without any date/time information. You can change the date/time pointer of raw or independent columns but not of computed columns A computed column inherits the date/time pointer of the column from which it is transformed.

You can time merge all or some of the variables in a dataset. You can select the date/times and the variables that are unattached. When you merge a date/time variable, all other variables that reference it are also merged; the original date/time variable is removed from the after-transforms dataset and replaced with a new merged time, and the date/ time pointers are changed to the new merged time. When an unattached column is time merged, its values are not changed, but its date/time pointer is set to the new merged time variable.
