forward/rewind not working as intended

[aodj]

When attempting to use spotify forward 5 it instead jumps to 5s into the current track. When attempting to use spotify rewind 5 it instead restarts the track at the beginning (ie: jumps to 0s).

$ spotify forward 5
Jumped to 0min 5s
$ spotify rewind 5
Jumped to 0min 0s

Here's a better example using chained commands:

$ spotify info && spotify forward 5 && spotify info
