A timestamp is a column that captures the time at which the inference was made. This is typically the time at which the inference was made in production.
Timestamp columns are prefixed with the category :timestamp: in the column name. Timestamps are represented as the following data types:
Timestamp columns MUST be singular, meaning that there is only one timestamp column per record. Timestamp columns are typically used to perform time-series analysis.
There are no reserved specifiers or names for timestamps.
Here are examples of a set of timestamp columns:
