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
