date/time in png header

[Former user]

Having the current date and Time in the saved png files is nice - at least until you want to "diff" those png files or supply a hash so people can check/compare their own files, because that won't work.

Suggestion : Make it optional.

I am not sure you'd get the same file when you drop the date.

Even leaving comments and the compression levels aside, the compression algorithm might make different choices on different platforms/machines/OSes, no?

A valid point, considering the many different flavours of posix systems out there. I was thinking of Windows, and my own short "duh" moment when I was trying to figure out why the files didn't match.

I think this can be closed ... png hash will be inconsitent anyway so we used mzd_hash to provide a consistent check value.
