Renamed variable to something more illuminating.

The variable storing start time of playbook run was named 't0'.
While perfecly fine from a functional standpoint,
and also in statistics and physics with subscript,
it is nonetheless a bit hard on the eye.

Tests were adjusted to reflect new var name.
