so basically my problem is that I want to continuously run my data collection, but I only want to send the time to the dashboard every say minute or so, this is just to reduce the amount of data points that I pull out of the plotter for excel. I tried looking online for some help but I am just getting more confused, if anyone could help that would be great. I just took out my username and password info because I was not sure if it mattered.

    if (time.time() > timestamp + 60):  
        //do whatever you want
        timestamp = time.time()
        i = i+1
