When counting down with 12H time format, if counting down less than an hour it would appear as "12:05:00 AM" instead of "00:05:00", even forcing time format to "HH:mm:ss".
The time format was being ignored since the phone had an unconpatible locale with this time format. Using en_US_POSIX locale fixes this issue.
