   Replaced and extended code that was removed from png_set_filler() in 1.0.1a.
   Fixed a bug in png_do_filler() that made it fail to write filler bytes in
     the left-most pixel of each row (Kevin Bracey).
   Changed "static pngcharp tIME_string" to "static char tIME_string[30]"
     in pngtest.c (Duncan Simpson).
+  Fixed a bug in pngtest.c that caused pngtest to try to write a tIME chunk
+    even when no tIME chunk was present in the source file.
   Fixed a problem in pngrutil.c: gray_to_rgb didn't always work with 16-bit.
   Fixed a problem in png_read_push_finish_row(), which would not skip some
     passes that it should skip, for images that are less than 3 pixels high.
