Those should be execution times like in default format:

```
real	0m0.006s
user	0m0.002s
sys	0m0.004s
```

So I thought `%R` stands for real, I will double check on that.

@joshk, yeah T is missing sorry - it needs some work still as I didn't test it properly. So I tested those concepts in some dummy bash scripts, but still haven't checked properly with whole travis stack.
