I have a string that reads "12-38-09" and a 1x6 char that is 123804. I need both of these to be displayed as a HH:MM:SS format of time. How can I do that? Also, I am not including dates, just times.

Unfortunately, the 'inputformat' option for duration() is much less flexible than for datetime()
duration(sscanf('12-38-09', '%2d-%2d-%2d').')
duration(sscanf('123809', '%2d%2d%2d').')
If you have a bunch of these, you might alter the code a bit depending on how they are stored.

duration(sscanf(eyeTrackingTime, '%2d-%2d-%2d').')
duration(sscanf(eyeTrackingTime, '%2d%2d%2d').')
If you do not know ahead of time whether the variable will have the dashes or not, then we could deal with that too.
duration(str2double(regexp(eyeTrackingTime,'\d\d', 'match')))
You might need .' after the )) before the third )
