Tips & How to Use
- 1. Paste an epoch timestamp or pick Now.
- 2. Choose a time zone to format output (UTC is always shown as well).
- 3. For date → epoch, enter a date/time and choose how to interpret it (UTC or selected time zone).
- 4. Use Copy or Share Link to keep your results.
- 5. We auto-detect seconds vs milliseconds. You can force the mode if needed.
Pro Tip: Mind Daylight Saving Time (DST). Interpreting local date/time depends on the chosen timezone and DST at that date.
