Hi bibo,
unfortunately I cannot download anything from your linked website: all I get (behind company firewall) is an empty page…
That's exactly the reason why we always ask for attachments in this very forum - please don't use 3rd party websites!
You were able to attach your main VI here, so please attach some subVIs. (Atleast the "Time" subVI you have problems with!)
Best regards,
GerdW
