Hello,
I submit this very simple workspace that writes three text files containing the current date obtained in different ways from a private parameter (Today).
I get 3 different files when I thought I could get the same 3 files. Moreover, there is no problem to create directories containing the date.
Unless I'm mistaken, it looks like a bug. Especially since when I designed the workspace, test1.txt contained the expected result... If the .fmw is copied or moved, the problem occurs.
I ran this workspace on version 2020.1 (FME(R) 2020.1.1 (20200817 - Build 20614 - WIN64).
