I am trying to time a program that I have written, but I need to break it up into different intervals to account for the time I spend inputting data and the time the prorgam actually calculates the information. On my computer, the program runs very quickly, so getting the time in double precision would be prefered. I found the dsecnd command in compiler documentation, but it doesn't give much info on how to use. When I try to compile my program, I have gotten some different errors. First, it said dsecnd did not have a type and that it must have an explicit type, so I declared dsecnd to be double precision. Then it said it is an unresolved external symbol.
Searching around the internet, I cannot seem to find any examples of dsecnd being used. Does anyone have an example, or any suggestions?
