Date() x-axis data gets incorrectly retrieved when getting the closest point in the 'plotly_click' function

[finger563]

Appears to be offset by timezone of the computer on which it's running.

E.g. when I create a data point with a certain epoch time in milliseconds and then click on that data point and get it's x-value (after using point.xaxis.d2l(point.x)) I get the wrong number of ms since the epoch.

I think the discussion in #1532 will answer your questions.
