MIDI encodes onset and offset separately. However, in this context "offset" should be thought of more like "key release". If the selected instrument is, say, an organ (no note decay), the encodings should give correct timings as- is. But for instruments with lots of decay (tonal percussion, struck or plucked strings, etc) the perceptual offset may come sooner then the key release. MIDI also includes an optional separate sustain, which would mess with offset times. One neat thing about MIDI is that you can easily edit the MIDI file to change instruments and settings "after the fact" of the original recording. So you could force all instruments to be non-decay types, and listen again to make sure the result seems acceptably faithful to the original.
