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 png_convert_

from_time_t() function calls gmtime() to convert from system clock

time, which returns (year - 1900), which we properly convert to the

full 4-digit year. There is a possibility that applications using libpng

are not passing 4-digit years into the png_convert_to_rfc_1123()

function, or that they are incorrectly passing only a 2-digit year

instead of “year - 1900” into the png_convert_from_struct_tm()

function, but this is not under our control. The libpng documentation

has always stated that it works with 4-digit years, and the APIs

have been documented as such.
The tIME chunk itself is also Y2K compliant. It uses a 2-byte

unsigned integer to hold the year, and can hold years as large as

65535.
zlib, upon which libpng depends, is also Y2K compliant. It contains

no date-related code.
