  * Y2K compliance in libpng:

  *    Libpng only has three year fields.  One is a 2-byte unsigned integer
  *    that will hold years up to 65535.  The other two hold the date in text
  *    format, and will hold years up to 9999.

  *    The integer is
  *        "png_uint_16 year" in png_time_struct.
