Add binary target to use "cargo install"?

[IngwiePhoenix]

I often use https://time.is to convert timezones, getting this from the CLI would be neat!
However, when running cargo install when i get this:

error: there is nothing to install in `when v0.1.4`, because it has no binaries
`cargo install` is only for installing programs, and can't be used with libraries.
To use a library crate, add it as a dependency in a Cargo project instead.

Could you add a binary target to solve this? Thanks!

It can be installed from github as shown in the readme. I do not own the when package on crates.io and I haven't published it to crates yet.
