Searched for 'elapsed time' posts and found two, but they were over my head (LOT of smart people on this forum) and I'm running out of time (patience, and others).
Column A is in seconds. Run this script on this data ...
aa=col(1)[1]; reads the first value in column 1 which is "Time" and since that has no numeric value, aa get assigned as a missing value. Math using missing values results in missing values.
To zero-base your time data, change aa=col(1)[1]; to aa=col(1)[2];
and your loop only needs to start at 2: loop(nn,2,wks.maxrows)
