Why does UpTime Screen Saver hide zero values in the time display?

Starting in version 1.02, UpTime Screen Saver automatically hides zero values for cleaner, more readable output. For example, it displays "1 week, 1 hour, 15 minutes" instead of "1 week, 0 days, 1 hour, 15 minutes." This makes the uptime easier to read at a glance.
