RDT: Reversible Data Transforms
Generic PII Anonymization
＊ Deep Data Understanding
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.
