Date & Time
Convert timestamps, compare two instants, and add or subtract time — with timezone views.
What you can do
- Parse Unix seconds/ms, ISO 8601, dates, and times
- See one instant in many formats (ISO, RFC, components, Unix scales)
- Browse timezone converter with favorites
- Difference between source and target
- Add/subtract years through seconds from source
Source defaults to current Unix time; target defaults to now (live optional).
Source & target
Each column has:
- Text input with auto-detect or manual format
- Pick calendar
- Now toggle (target) — updates every second
- Converted list with copy buttons per format
Auto-detect examples
| Input | Detected as |
|---|---|
1715346265 (10 digits) | Unix seconds |
1715346265000 (13 digits) | Unix milliseconds |
2024-05-14T14:30:00Z | ISO 8601 |
14:30:00 | Time today (local) |
Timezone converter
Table of the parsed instant in local, UTC, common aliases, and IANA zones. Star rows to pin favorites (saved in this browser).
Results column
Difference (target − source): days, hours, minutes, seconds, relative phrase (“in 2 hours”, “3 days ago”).
Add/subtract: Shift source by calendar offset; view result in local and favorite zones.
Reset sets source to now (Unix) and target to current ISO.
Tips
API createdAt: Paste Unix ms → read ISO and local from Converted.
Deadline: Source = now, target = deadline ISO → read Relative difference.
Colleague’s zone: Star their timezone, copy converted string.
Keep in mind
Time-only input anchors to today locally. Add/subtract uses UTC calendar fields — may differ from timezone-aware “add one month” around DST. Difference is elapsed time, not calendar months between dates.
App shortcuts
| Action | Shortcut |
|---|---|
| Search tools | ⌘ K |
| Close current tab | ⌘⌥E (Ctrl+Alt+E on Windows) |
Note: ⌘W closes the browser tab. ⌘⇧E focuses the Explorer in Cursor/VS Code. Use ⌘⌥E (Ctrl+Alt+E) to close the current tool tab (click inside the app first so the IDE does not steal the shortcut).
