Go Map!! does use the iPhone camera and Apple's Vision framework to 
suggest the appropriate opening_hours value. [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.
