Robocopy shows what seems to be the time it took to do the copy...but it shows two
The time under the total column is the sum of:
Copied Time - spent copying files (excluding retry wait times)
FAILED Time - spent waiting between retries for failed operations
Extra Time - spent scanning directories and performing other functions
