We have a batch time tag on our fermenters called TFT ("total fermentation time") that is created by the process control system as a string in the format "dd:hh:mm:ss". I am interested in converting this value into a float32 value in seconds that can be used directly for calculations over the time course of the run. So for example, we want to convert a TFT string value of "1:12:30:15" (which is 1 day, 12 hours, 30 minutes, 15 seconds) into a float32 value of 131,415 seconds. From there it would be very easy to convert to hours and perform productivity calculations. Does anyone have an idea of how to use a performance equation or analysis in Asset Framework to accomplish this?
