Issue confirmed.

Also if copy "00:00:00" inside Start Publishing Time is set like "10:59:09".

@vdneut does #17703 solve the problem?

edit:

Remove time part of the date/time field

That will not reset the time, you need to set it manually e.g. 00:00:00

@dgt41 i used latest staging for Test, as #17703 is merged it don't help in this Case.

@franz-wohlkoenig read my previous comment, atm deleting the time is not reseting it, if that's a bug then let's make a PR...

EDIT: my feeling is that in a calendar field that time is required if none is provided then current time is used, I don't remember the actual, but I bet this is the current functionality

@dgt41 i manually appended 00:00:00 and it gets resetted by actual Time (Comment)

I would also expect that empty time is removed by "10:04:09" and not by "00:00:00".

Previous behavior was: if you remove time string like 12:12:12 in any case, the time was allways set to 00:00:00. I'm sure because I do this every week for > 5 years now. It also makes sence as having only a date, one would expect the time would be midnight.

@vdneut thanks for Info, didn't know that.

At my site setting publishing end date to something, and leafing created and start publishing dates clear, then saving, causes end publishing date to get hosed. This is a Medium-High impact error as we use an ent date on most of our articles (30-60/month). Please see pefore/after screen shots.

@jimbrooking I can't reproduce this.

It appears that you are using the TinyMCE Editor. TinyMCE does not exhibit the problem. JCE (version 2.6.19) is where my problem lies. Should this be taken up with the JCE people instead of Joomla?

Thanks for checking.
