🔍 Key Concepts

• Understand that chronometer rate is the change in error per 24 hours • Compare yesterday’s reading error and today’s reading error against true GMT (1200) • Determine whether the chronometer is gaining or losing time each day

💭 Think About

• First, decide what the error was yesterday at the 1200 GMT tick: was the chronometer ahead or behind, and by how many seconds? • Then, decide what the error is today at the 1200 time tick: ahead or behind, and by how many seconds? • Finally, find how much the error has changed in one day and whether that change is positive (gaining) or negative (losing).

✅ Before You Answer

• Be clear on the sign convention: a fast chronometer has a positive (gaining) error; a slow chronometer has a negative (losing) error. • Carefully subtract yesterday’s error from today’s error to get the rate per day. • Confirm that you’re using 24 hours between ticks and not mixing up which error comes first in time.
