The federal Minimum wage in the US is $7.25 per hour. Ten states have higher minimum wages with Rhode Island clocking
in 50 cents higher at $7.75.
What is the meaning of clocking? Why not use "closing"?
I think the existing answers are potentially misleading. It's true that to clock in originally gained currency in the 40s in respect of workers recording the time of starting work (often, in a factory, where they might also clock on, and clock out or clock off when they finished work).
But in recent decades, the specific phrasal verb clock in has acquired another sense. It's now often used to mean record / achieve a "score" in a competition (where OP's "minimum wage comparison" can be seen as a "competition").
This usage is particularly favoured where the "score" values are time-based, but OP's example is by no means uncommon. Another very similar idiom is clock up - to reach a particular number or amount.
Note that the more common phrasing here would be with Rhode Island clocking in at 50 cents higher. In such contexts, to clock in is usually followed by at [the actual recorded value], but in this specific case that would be clumsy - since the actual value is expressed as 50 cents higher at $7.75, we'd have two occurrences of the same preposition in undesirably close proximity.
Having said all that, I agree with other answers/comments making the point that OP's cited usage could (but doesn't have to) be seen as a punning allusion to the factory timekeeping origin of the expression.
Finally, I'll just say that if the writer had used clocking up instead of in, he wouldn't have had to think about whether to follow it with at (which is rarely used after up). But then his pun would be diluted.
Think of it as "clocking in", not just "clocking", and I believe you'd understand why.
Though you can write "closing in" instead of "clocking in" and the meaning will still be roughly the same, using "clocking in" makes the line much more interesting, in my opinion.
Workers usually need to clock in and clock out of their work. The basic sense of clock is to measure or record something (though it's usually about the speed). By playing with words, the sentence jumps off the page and puts me into the context of labors and minimum wages instantly.
Here are the definitions for "clock in" and "clock out" from the Free Dictionary:
clock in - register one's arrival at work
clock out - register one's departure from work

It's the time you spent working in a factory or office. If you say you're on clock, that means you're in working hours.
I work(on clock) here for one hour and will get $7.75
