Just encountered a bug in robocopy:

That Total Time is a little off. Actual run time is about 19 hours. The H:M:S values are each quite close to a max unsigned integer (presuming the seconds value has a character truncated). Converted to a signed int makes it about -72 hours. Not sure what went wrong there!
