在如下两个例句中，均存在着“谓语 + 宾语 + off the clock”如此一种组合：
1. Just as you spendmoney to build market share, launch new products and increase brandrecognition, be willing to invest in initiatives that will change longstandingworkplace practices—like performing preliminary activities off the clock orattending midday meetings—that put you at risk.
2. When aprofessional service firm refuses to have any conversation off the clock or acompany never leaves any money on the table in a negotiation, I always becomeconcerned that they really do not understand that they are in the relationshipbusiness where referrals and word of mouth mean a lot.
请教曹老师，这两句话中的介词短语“off the clock”到底充当着“状语”还是“后置定语”？
二个句子中的off the clock都是状语。
