Thanks a lot to all of you for finding and fixing this bug!
It is working in Gwenview as of today's KDE neon unstable edition.

Tested https://phabricator.kde.org/P170 + https://phabricator.kde.org/differential/diff/33278/ and it works for me.

Please consider to bring this patch upstream soon "as is" even if if it can be possibly improved.
I was asked by nervous colleges to solve this problem for them. It occurred for them in the context of cropping/save as.
This patch will do the job.
Thanks Peter for the finding, answering my "unrelated" questions and pointing me here!

No, I don't have commit access.

works for me now / ready to ship

Kai Uwe, David any ideas how to proceed with the change last week?

It supressed the seconds to be copied into the clipboard in case of the per minute update of the display.

I think you get it much faster done. Please do it.
I'am sitting in a hotel now without tools do to something software related :-(

Ah, I got it now and will try it.

Sorry for not understanding the (perhaps your?) problem with the seconds.
Do you like to express that you:
1.) do not get seconds at all (erverytime 00 or 59) or
2.) do not get an actualized value of seconds (or time) in very the moment of clicking the intended format or
3.) can have a platform related problem or
4.) someting else?

Thanks for the feedback.
It was integrated to my best understanding and works for me.
