Sets the pattern for the time that is displayed in the control bar, where h is hours, m is minutes, and s is seconds.
The number of letters used for each time unit determines the number of digits to display for the unit. If the number cannot fit into the given digits, the equivalent value is displayed in the subsequent unit.
For example, if the current movie time is 67 minutes and 5 seconds, the time pattern m:ss shows as 67:05. The same time is displayed as 1:07:5 if the given time pattern is h:mm:s.
