Brings it inline with description (being previously scheduled start date values,
which include DateTime), existing examples (eg-0172, eg-0202), and usage
practices around the web (including Google's "Event Structured Data" docs).

Release v3.1 (2016) added DateTime to startDate, but previousStartDate was
unchanged at the time.
