Time function
The Time function is used to assign the elapsed time in seconds since
system startup or assign the elapsed time in seconds equal to, or
closest to (but exceeding) a specified interval.
To insert the Time function:

Time function.
Time function syntax
A = Time()
Assigns the elapsed time in seconds since system startup.
A = Time(Interval)
Assigns the elapsed time closest to a specified interval.
A = Time(Interval,value)
Assigns value changes over a specified time interval.
Example:
V = Time(10sec,C1)/Time(1sec)
Uses an elapsed time interval and a value change captured at
channel input C1 over the same interval to calculate the exact
velocity of the motion of C1.
The approximation of specific time Intervals is necessary
for the exact calculation of velocity and other time related
quantities because the system clock is not a precise
timekeeping device. By returning a time interval that is
known precisely, exact calculations of time related
quantities are possible.
