clock display is weird with long interval (-i) times.

[lindes]

When run with, for example, -i 120, the clock updates along the bottom of the graph are... weird. E.g. one big string at the right side, which contains:

^^^^^^11:59^^^^12:1

Reported by @Telofy on twitter (thank you, @Telofy!):

"when I use a large -i (e.g., -i 120), the time labels look weird"

Fixed in my local tree. Running -i 120 for a while to confirm before submitting; expect it soon.
