When doing some physics (like quantum field theory) it is useful to adopt unit conventions where c=1. Using this convention, space and time would have same dimension. How long a time is 12 parsecs? It's the amount of time it takes light to travel 12 parsecs.
In this unit system, speeds are dimensionless which might explain: "She'll make .5 past light speed."
