This question can't be answered without knowing the current time. To find out what time it was 54 minutes ago, 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 11:59 AM: 54 minutes ago it was 11:05 AM.
- If it's currently 12:00 AM (midnight): 54 minutes ago it was 11:06 PM the previous day.
You can easily calculate this yourself using a clock or your device's time display.
