Not that there was any doubt, really, but I just happened to be logged in when my Mini-Mines completed, and saw the same bug as you did. That old mine o' mine is showing 49710:06:28:08, which is:

(((((49710 * 24) + 6) * 60) + 28) * 60) + 8 = 4294967288



And as noted, (2 ^ 32) - 1 = 4294967295, so I guess I looked at it 7 seconds after the rollover.

But of course I'm playing on Windows, so this still doesn't address your question about whether the display bug occurs on other devices as well.
