I'd have to say "No."

Nutshell: time, itself, uses essentially no time -- given the speed of 
computers these days, likely in the microseconds, whereas doing things 
like authentication checks and stuff (needed by sudo) can take into the 
milliseconds.  Personally, I have no idea why it was in that command in 
the first place.  It would have no real affect on functionality.  
Perhaps something was taking longer to run that expected, and they were 
doing a crude attempt at diagnosing things?  If so, strace, while vastly 
more complex, is also vastly better-suited for profiling.
