Define timestamp columns for the dataset.
The method defines columns to be used as timestamps. Timestamp columns on a dataset
make it possible to treat the data as time-series data and enable additional capabilities.
When a dataset has both fine_grain_timestamp and coarse_grain_timestamp defined
specified, the two columns should represent the same timeline.

)The Tabular Dataset object.
The name of column as fine grain timestamp. Use None to clear it.
The name of column coarse grain timestamp (optional). The default is None.
Indicates whether to validate if specified columns exist in dataset. The default is False. Validation requires that the data source is accessible from the current compute.
