Blurring Date Values

Blurring Date Values

Mask a date as a variance of the source date by configuring blurring. Select a unit of the date to apply the variance to. You can select the year, month, day, or hour. Enter the low and high bounds to define a variance above and below the unit in the source date. The Data Masking transformation applies the variance and returns a date that is within the variance.
For example, to restrict the masked date to a date within two years of the source date, select year as the unit. Enter two as the low and high bound. If a source date is 02/02/2006, the Data Masking transformation returns a date between 02/02/2004 and 02/02/2008.
By default, the blur unit is year.
