I'm not sure if this is an expected behavior, but I just thought this is quite weird, so I'm posting this here
Those blocks in left and right is almost identical, except for that the left one has <set "x" to get "name"> block.
A set of blocks here is meant to subtract the second item within 3-items-list, while I'm trying to make a custom procedure that returns interval time between two time list.
So the variable "x" and "name" is identical, until item 2 of "name" gets replaced with item 2 + 1 "name".
and a blockset returns subtraction between item 2 of each list,
while the left one returns 0 while the other does 1.
set "x" to get "name" does make the difference here, as shown in screenshot
and I thought this is unexpected, because that action goes before replacing item 2
and one more, the pattern S in Clock.FormatDateTime shows a tenth of second, while this page says it stands for millisecond.
