${starttime} is a local variable, so we need to pass it to "Save Setup Time"
this is not seen in older versions of robotframe work because variable
scoping was not as strict. In the new RF2.9, local variables do not
"leak". This is probably a problem in many places, but I found this one
for now. It breaks on my local RF2.9 environment. Works with this
patch and should not have any problems upstream with older RF versions
