In a related point, we need to be careful that when trying to translate 
all of the data in opening_hours into something that a computer can 
understand that information isn't lost.  "Breakfast until 11am" usually 
makes perfect sense to a human in the context of the rest of the tags on 
an item.

As another example, this pub node:

http://www.openstreetmap.org/node/1479235861/history

had opening hours of "12:00-late" changed to "12:00+".  In context (a 
pub in an old English town centre) "12:00-late" carries meaning that 
"12:00+" does not, despite it confirming to some rules artificially 
imposed by https://github.com/ypid/opening_hours.js .

We certainly shouldn't be mechanically changing opening_hours tags that 
don't quite correspond to those rules when we don't quite understand the 
cultural context of the original tags.

Cheers,

Andy
