If REST is included in the first TIME on a time-range timestamp then the entire timestamp becomes a single range-less timestamp. To test I used the following test document:
```
[1970-01-01 Thu 8:15-13:15foo]
[1970-01-01 Thu 8:15foo-13:15]
```

The first line parses as a timerange from 8:15-13:15.
The second line parses as a single timestamp at 8:15.
