What is the access time setting for a data set and should I turn it on or leave it off as default?

The access time for a file is an addition attribute where the file system will record the time and date of any read operation on the file.  It is default because even snapshots will read the file causing massive additional attribute metadata writting to the file system.  Therefore it is recommended in most all cases to leave it off and only for edge cases where the application must use access time turn it on.  The setting is per data set.
