The expression "against the clock" means to do something as quickly as possible because there is a limited amount of time. It can be used in various situations, such as when you have a deadline to meet or you need to finish a task before a certain time. For example, if you are taking a test and you realize that you only have five minutes left, you might say, "I'm racing against the clock to finish this test." Or if you are cooking a meal for guests and you are running behind schedule, you might say, "We're cooking against the clock to get dinner ready on time."
