How to get the exact time of a MIDI event

Question

I am trying to read a MIDI file, and I want to determine the exact time of a NoteOn event from it in C #.
I tried to use absolute time, but the result was something like 256632.
What is this number? This is a line of my code that returns the time:

(note as NoteOnEvent).AbsoluteTime

Answer 1

A MIDI file contains only incremental times. Included as a variable length between 1 and 4 bytes before each MIDI event. The library you use is useful for providing you with the AbsoluteTime property. It is simply calculated by summing incremental times for each event.
