When I use the DateTimeStart function in two different locations in my workflow, I sometimes get different results that are off by one second. This wreaks havoc on my workflow as I rely on the original time stamp at various points in my workflow.
Mmm strange indeed.
I suggest generate once, and then append the field to whereever it is required.
This is still erroring when I run a time stamp in a batch macro. Each iteration of the macro is generating a different time stamp, but I just want the time stamp for when the macro first began running, not each iteration time.
