time labels on reversed horizontal axes with rangebreaks are slightly off

[archmoj]

Out of the mocks here, the only one that bothers me is axes_breaks-night_autorange-reversed.png

The "05:59" labels are weird, why don't they say "06:00"? But everything else is great, and even this one is more correct than before, just uglier. It's an obscure enough edge case that I'd be happy merging and releasing like this, and flagging this for follow-up later.
