Uptime
Let's go back to LabVIEW. Have you ever wondered what's the meaning of the "Time" item in an event structure timeout case? Well, it's just the uptime , the time in milliseconds since the computer was started. Download (VI for LabVIEW 2016) So, if you need to recover the uptime you can use a VI just like this, an event structure that immediately closes and returns that value. It's a nice alternative for calculating execution times or, broadly, any instance when you just need relative and not absolute time measurements.
