I am pretty happy with the default for how dates ticks
are updated with zooming the plot with the navigation
toolbar...until it gets down to the level of hours.
Hours are by default displayed in a format like:
"23:00:00 UTC". How can I get it to display it in a
more common way, such as "11:00 pm", or better,
"11 pm, 3/15"?
Everything else should stay the same.
