smallest possible range/body

if you provide an input like `say hi at 5pm`, the matching range and body will be `at 5pm`. I'm trying to figure out if there is a reliable way to just get the range of the `5pm`, ignoring the `at`. This does seem to have some nuance as well, for example `say hi in 5 minutes` should still be `in 5 minutes` and not `5 minutes`. Is this currently possible with the data being parsed/returned?

Start by reviewing the examples in the issue and the Duckling parsing and returned-data behavior they refer to. Determine whether the existing result data can distinguish the smallest meaningful range for “5pm” while preserving the full phrase for “in 5 minutes”; done requires a documented answer or a clearly scoped change proposal.
