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.
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.
Encode datetimes as numerical values based on the Unix timestamp.
Encode datetimes as numerical values using the least common denominator.
