```suggestion
<td>During schema inference (<code>inferSchema</code>), attempts to
infer string columns that contain dates or timestamps as <code>Date</code> if
the values satisfy the <code>dateFormat</code> option and failed to be parsed
by the respective formatter. Attempts to parse timestamp columns as dates using

1. Re-order sentence for readability
2. Removed: "When used in conjunction with a user-provided schema" because
parsing timestamp columns as dates happens regardless of whether there is a
user-provided schema
3. Split sentence at comma for readabilityWhen used in conjunction with a
user-provided schema
