Title: [Plots] Reset time span with corner reset

On click of corner reset button, reset time
span based on what is observed in settings.
Previously, the actual current time span
was being read, which preserved zoom when
corner reset button was clicked, which is
incorrect. This causes nasa/mct#271.
