Timestamp Shift (TimestampShiftGenerator)

The Timestamp Shift generator shifts timestamps by a random amount of a specific unit of time within a set range.
The Timestamp Shift generator does not support linking. It can be self-consistent or consistent with another column. You cannot configure differential privacy.
The metadata object is populated from the TimestampShiftMetadata object, which includes:
  • For text source columns, the format of the datetime values in the original data.
  • For integer source columns (Unix timestamps), the unit to use.
  • The part of the timestamp to shift.
  • The minimum amount to shift the value by. Use negative numbers to move the value earlier.
  • The maximum amount to shift the value by.

Example replacement

The following example replacement for the Timestamp Shift generator updates text timestamps in the format yyyy-MM-dd. The generator shifts the day anywhere from 3 days before the current day to 3 days after the current day. The generator is consistent with the order column.
