Chrome uses TimeDelta class to represent a duration of time. When UX shows this duration of time, it can use 4 different formats. An example is that if the time duration is 15 hours, 42 minutes and 30 seconds, UX will show:

1) 15 hours, 42 minutes, 30 seconds, if format is DURATION_WIDTH_WIDE;
2) 15 hr, 42 min, 30 sec, if format is DURATION_WIDTH_SHORT;
3) 15h 42m 30s, if format is DURATION_WIDTH_NARROW;
4) 15:42:30, if format is DURATION_WIDTH_NUMERIC.

However, when it is above 24 hours, say the time duration is 25 hours, 42 minutes and 30 seconds, and the format is DURATION_WIDTH_NUMERIC, then:

What is the expected result?
25:42:30

What happens instead?
1:42:30

This is found if I change "15 hours" to "25 hours" in TimeFormattingTest.TimeDurationFormat. Basically the hour value is mod by 24.
