[PT/ES DateTimeV2] "15 to..." time expressions aren't supported

[cahann]

PT - 15 vs. quinze: quinze para as 8 Returns T07:45/T19:45 15 para as 8 Returns T08/T20

ES - 15 vs. cuarto vs. quince: 8 menos cuarto Returns T07:45/T19:45 8 menos 15 Returns 15, 8 8 menos quince Returns 15, 8

(Note: 8 menos 15 isn't supported in ES, but common use is cuarto) (Note: in PT 15 is less common than quinze, but it can be used if you're writing in a hurry)

We'll consider supporting these less common cases, but currently it's not considered high priority.
