Batch date changing of multiple folders and all files

[crazyman]

I can do that by changing attributes, but only for "modify date/time" column which is currently viewed. I cannot adjust view also for "created" column (how to set the view mode?), so I don´t know whether this function works also here.

Use "Change plugin attributes" field on "Change attributes" window.
Plugin: tc
Property: creationdate
There's no need to activate any special view mode (custom columns).
