Announce chronometers with time-unit words.
Instead of just using the visible representation for
accessibility, for which "00:15" is announced as "zero
fifteen", we now say "fifteen seconds".
Similarly,
00:00 - "0 seconds"
01:00 - "1 minute"
02:05 - "2 minutes 5 seconds"
1:00:00 - "1 hour"
2:00:02 - "2 hours 2 seconds"
2:01:02 - "2 hours 1 minute 2 seconds"
-5 - "5 seconds" (what are we, Mission Control?)
