<trivia>

Personally I'd have written it as $START_TIME, but as a bit of Perl
trivia you might not realize $t0 is a commonly used and undestood
variable for dealing with a start time in Perl in the same way that
`i` is common for dealing with array indexes in C.

I.e. someone used to Perl will immediately think "oh that's the start
time" having seen it hundreds of times before, but someone not used to
Perl will go "what's this t-zero thing?".

Meanwhile some Lisp programmer is wondering what the hell "i" means in
your C for-loops, iterator? :)
