HASHDOB masking function

Issue/Introduction

We are using Fast Data Masker to obfuscate dates of birth. In our testing, all the dates were masked as expected except for two dates that are in the far past, and far future:

• 1800-01-01 (far past)
• 2049-06-17 (far in the future)

Why did these two date not get masked?

Environment

Release : FDM 4.10.77.0

Resolution

In order to mask dates that are in the distant past, you will need to set the HASHDOBEARLIESTDATE option in the format of YYYY-MM-DD.

For example: HASHDOBEARLIESTDATE=1800-01-01

OR

HASHDOBEARLIESTDATE=1799-12-31 

to avoid any time zone difference.

As for dates that are in the future, since this date is higher than the current date, it is considered an invalid date by the HASHDOB function. Therefore, the date is not masked.
