Inconsistency for TimeIntervals

[joffreyvillard]

Hi,

I found the inconsistency below for TimeIntervals (see the to field)
In such sentences, we know that the expected result depends on the user (there is not a single good answer that everyone agrees with), but it seems that at least the output should be consistent, so that each application could apply its own rule.
What do you think?

EDIT: btw, the reported issue about grains missing for TimeIntervals (#678) prevents from implementing a robust workaround for this one :(

Thanks in advance!
