The extra tags are zTXt chunks.
- 0 date:create: 2010-09-13T12:59:09-04:00
1 date:modify: 2010-09-13T12:59:09-04:00
We'll revise png.c to avoid writing them.
Meanwhile, you can use
Code: Select all
pngcrush -rem text file.png file_clean.png
to get rid of them.

Or use:
convert 1x1_.png -strip +set date:create +set date:modify 1x1.png

In the current version of ImageMagick, the -strip option removes the create and modify date properties.
