Final answer:
To convert military time to regular time, subtract 12 from the hour if it is greater than 12.
Step-by-step explanation:
To convert military time to regular time, you need to understand that military time uses a 24-hour clock while regular time uses a 12-hour clock. To convert 15:17:52 to regular time, subtract 12 from the hour if it is greater than 12. In this case, 15 - 12 = 3, so the regular time is 3:17:52 PM.
