1 hour ago
One hour ago is the recent past — useful for logs, timestamps, and "when did that happen" checks.
What time was it 1 hour ago?
"1 hour ago" means the current clock time minus 1 hour. Starting from 3:00 PM, counting back 1 hour lands on 2:00 PM, which falls on the same day.
How it works
Timesabout subtracts 1 hour from the exact moment you load the page and rolls back to the previous day when the subtraction passes midnight. The figure recalculates every second.
