You can change the seed value for a field to return repeatable datetime values between the fields.

Key date masking can mask dates between the years 1753 and 9999. If the source year is in a leap year, the

masking

task returns a year that is also a leap year. If the source month contains 31 days, the

masking

task returns a month that has 31 days. If the source month is February, the

masking

task returns February.

When you perform key date masking on Salesforce data, the

masking

task can insert dates up to 4000. If the masked date value is more than 4000, the

masking

task fails and throws exception.
