[1] However, all Vision gives Go Map!! is the signposted text it detected as an unstructured string; it's up to Go Map!! to parse it into something machine-readable. As far as I can tell, Go Map!! requires the sign to be in proper 12- or 24-hour format, but it doesn't specifically reformat opening hours that extend past midnight.

That makes far more sense - I thought that it would be about doing it
on opposite direction: turning opening_hours tag into a structured opening hours data
using "AI"

Turning image of opening hours sign into text, that into structured opening hours and
asking user for confirmation makes far more sense and I should thought about it.
