Hey, thanks for your input on this! :)

The output I showed above was just to illustrate, that i want real, sys and user time like in default format for time. `TIMEFORMAT` works fine for me.

When it comes to being friendly: I am not sure about every detail of this feature, but I assumed that I need something that can be parsed easily. So in travis web, I wouldn't show this format: `u=0.002:r=1.007:s=0.003`, I would rather show label similar to "fold" label with only real time written on it. This is only the matter of how we should show this on UI.

When it comes to `%R` and `%E`, what I see in man is:

```
E      Elapsed real (wall clock) time used by the process, in [hours:]minutes:seconds.
R      Number of minor, or recoverable, page faults.  These are pages that are not valid (so they fault) but which have not yet been claimed by other virtual pages.  Thus the data in the page is still valid but the system tables must be updated.
```
