To subtract hours from the current time, move backward by the number of hours you need. If you move past midnight, the date changes to the previous day.
For example, if it is 6:00 AM now, then 8 hours ago was 10:00 PM the night before.
This comes up often for logging events, tracking time stamps, and understanding time differences.
