*Y2K compliance in libpng:
*=========================
*October 3, 2002
*
*Since the PNG Development group is an
*an official declaration.
*
*This is your unofficial assurance that libpng from version 0.71 and
*upward through 1.2.5 are Y2K compliant. It is my belief that earlier
*versions were also Y2K compliant.
*
*Libpng only has three year fields. One is a
*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.
*The strings are
*"png_charp time_buffer" in png_struct and
*"near_time_buffer", which is a local character string in png.c.
*There are seven
*png.c: png_convert_to_rfc_1123() in png.c
*(formerly png_convert_to_rfc_1152() in error)
*png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
*png_convert_from_time_t() in pngwrite.c
*png_get_tIME() in pngget.c
*png_handle_tIME() in pngrutil.c, called in pngread.c
*png_set_tIME() in pngset.c
*png_write_tIME() in pngwutil.c, called in pngwrite.c
*
* All handle dates properly in a Y2K environment. The
