Relevant note (my personal opinion):

"If you use "time", you are using the time command provided by bash.
However, if you use "\time", then you are using the time program that
is provided by GNU. GNU's time
give a WHOLE LOT more information than bash time. In particular, see
the -p and -v options. However, bash time gives you millisecond (10^-3
sec) precision while GNU time
only gives you centisecond (10^-2 sec), so bash's time is more
precise".  SALZMAN, Peter Jay. Available at:
