Hello, a fast search return Time::Piece to be agood candidate for such subtraction, but it seems does not handles milliseconds

# pay attention to MSwin32 doublequotes

perl -MTime::Piece -E "$t1=Time::Piece->strptime('23:58:59','%H:%M:%S'
+);$t2=Time::Piece->strptime('23:56:58','%H:%M:%S');say $diff=($t1-$t2
+)"

121

# or directly subtracting

perl -MTime::Piece -E "say Time::Piece->strptime('23:58:59','%H:%M:%S'
+) - Time::Piece->strptime('23:56:58', '%H:%M:%S' )"

PS Time::Hires and it's tv_interval supports millisecnds operations: see Re: time difference in milliseconds

There are no rules, there are no thumbs..
Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.
