Notes
Whole seconds
Seconds are treated as whole seconds. If you enter a decimal value, it is rounded down.
Copyable outputs
The result includes local time, time zone, ISO 8601, and Unix timestamps for logs and spreadsheets.
Common seconds-ago questions
Use this to keep everyone referencing the same timestamp in chat, tickets, or calendars.
Enter whole seconds. Decimal seconds are rounded down. Choose “Current date and time” to use a live base time that updates every second, or choose “Custom date and time” to work from a fixed reference.
The output includes the target date, 24-hour time, 12-hour time, and time zone, plus ISO 8601 and Unix timestamps (seconds and milliseconds). This is commonly used for time tracking, incident timelines, and “how long ago” reporting. Across daylight saving time changes, the clock time can shift by an hour even when the elapsed time matches the offset.
Seconds ago answers questions like: What time was it 90 seconds ago?
Notes
- Use “Custom date and time” when your baseline is not right now (for example, a shift start, a log entry, or a scheduled departure).
- Seconds are entered as whole numbers. Decimal input is rounded down.
- If the offset is 0, the target time is the same as the base time.
- The calculator uses your browser’s local time zone for the base and the displayed local time.
Using a custom baseline
Use this for incident timelines, logs, and “when did this happen?” questions.
The output includes the target date, 24-hour time, 12-hour time, and time zone, plus ISO 8601 and Unix timestamps (seconds and milliseconds). This is commonly used for time tracking, incident timelines, and “how long ago” reporting.
