There's no way to answer "What time was it 54 minutes ago?" without knowing the current time. To find out, simply subtract 54 minutes from the current time. For example:
- If it's currently 3:00 PM: 54 minutes ago it was 2:06 PM.
- If it's currently 10:15 AM: 54 minutes ago it was 9:21 AM.
You can easily calculate this using a clock or a digital timer.
