What is the default format for a Time data type?

The default format for a Time data type is hh:mm:ss. This format is standard for representing time, where "hh" denotes hours, "mm" denotes minutes, and "ss" denotes seconds. This approach allows for an unambiguous understanding of hours, minutes, and seconds, making it easy for users to interpret time data correctly. In applications like Alteryx and others that handle time components, this format is widely accepted since it aligns with common practices in programming and data processing.

The other formats provided do not align with typical time representations. For instance, mm:ss focuses solely on minutes and seconds rather than including hours, which is essential for a complete time representation. The format ss:mm:hh is not standard and would confuse the sequence of time components, while yyyy-mm-dd is a date format, not applicable to time data.
