Datetime

Datetime columns indicate a point of time. This can be at any granularity: to the nearest day, minute, second or even nanosecond. Typically, the datetime will be represented as a string.

For example, you might be storing the last day users have logged into your site.

Always double check to see if the datetime columns are being detected. A datetime column might be incorrectly detected as categorical if it's in a non-standard format.

General Datetime Transformers

These transformers encode your datetime data as numerical values, ready for data science and machine learning.

UnixTimestampEncoder

Encode datetimes as numerical values based on the Unix timestamp.

OptimizedTimestamp Encoder

Encode datetimes as numerical values using the least common denominator.

Differential Privacy Transformers

These transformers use differential privacy techniques to add noise or reshape your column of datetime data. As a result, your column — and any statistics about it — can be shared with differential privacy guarantees.
