Five Digit Time Conversion to Standard AM, PM time

I am using an IP camera to fetch the date and time of a particular Video. The date is in the correct format but time is actually a five digit number like this “33092”. What time format it is? and how I can convert it into standard AM PM time format in javascript?

I thought this is second elapsed since midnight but by converting it I am not getting the desired AM PM time.

RESULT OF API TIME
