Date Shift

The Date Shift framework masks date values to different dates based on a specified range around the input value. Masked values are calculated algorithmically using the algorithm's key, so rekeying the algorithm will cause different outputs to be generated for each input. All valid input values will be masked to a new value, and the new value will never match the input.

As an example, a Date Shift algorithm with a minimum value of 3 and a maximum value of 5 with the unit set to Days will shift the input value from 3 to 5 days into the future. Dates may mask as follows:

• "2021-02-03 12:30:00" → "2021-02-06 12:30:00"

• "1905-12-10 00:00:00" → "1905-12-15 00:00:00"

• "2001-07-31 23:45:30" → "2001-08-04 23:45:30"

With roll enabled and the same configuration, a date at the end of a month will wrap around to the beginning of the month. Dates may mask as follows:

• "2021-02-25 10:00:00" → "2021-02-01 10:00:00"

• "1932-05-03 01:15:15" → "1932-05-08 01:15:15"

• "1999-08-31 18:30:00" → "1999-08-03 18:30:00"

All inputs with the same value masked with the same algorithm configuration will result in the same output values.
