highslide-software/highcharts.com — Issue #494: Highstock is a bit inconsistent with timestamp granularities

Under the hood, Highstock stores and interprets timestamps with millisecond granularity, but in the UI presented to the user, the granularity is inconsistent. See this screenshot:

The x-axis displays times in seconds, the tooltip displays timestamps in minutes, and the From/To text fields display times in days. For data that has fine-grained granularity, this inconsistency hurts.

I realize that I can override the contents of the tooltips, but having to reinvent the wheel just to get seconds granularity is kind of annoying. Also, not having seconds (or even minutes or hours) granularity in the From/To fields is a UX problem if the user wishes to zoom into a specific window that doesn't fall perfectly on day boundaries.
