 /**
  * Handles the conversion of a GenTime into a nicely formatted string, taking into account things such as drop frame if necessary.
  * Handles multiple formats, such as HH:MM:SS:FF, HH:MM:SS:F, All Frames, All Seconds, etc.
  *
  * For 29.97, 59.94, or 23.976 fps, the drop-frame timecode is used: For this frame rate, frames 0 and 1 are dropped every minute
  * but not every 10th to fix time shift; see https://en.wikipedia.org/wiki/SMPTE_timecode for details.
  *
  * To distinguish between normal and drop-frame timecode, they use a different format.
  *
  * HH:MM:SS:FF → Normal time code in hour/minute/second/frame format
  * HH:MM:SS,FF → Drop-frame time code
  *
