description:
make: fix local variable name for parsing arguments

The variable name 'arg' was misleading since after a successful
TryParseTime, it would no longer point to the argument of the variable
modifier, but to the _end_ of the argument.  To reduce confusion, use p
instead, like everywhere else.  This name is less specific, which is
still better than a wrong name.
