timestamp-viewer

Hover on any Unix timestamp in your code to see the UTC and local date/time, plus the ISO 8601 string — and edit it as a date in place.

Features

View

Put your cursor on any numeric timestamp (seconds or milliseconds, 10–16 digits) and a hover tooltip will show:

• UTC — date and time in UTC+0
• Local — date and time in your timezone
• ISO 8601 — canonical string representation

The extension auto-detects whether the value is in seconds or milliseconds:

Edit (new in 0.1.0)

The hover also includes an Edit as date... button. Clicking it opens an input box pre-filled with the current local date/time for that timestamp. Enter the new date/time (format: YYYY-MM-DD HH:MM:SS), pick the output unit (seconds or milliseconds), and the original timestamp in the editor is replaced.

You can also run the command Timestamp Viewer: Edit as date... from the Command Palette with the cursor on a timestamp.

Example: hovering over 1700000000 shows:

|             |                              |
| ----------- | ---------------------------- |
| UTC         | 2023-11-14 22:13:20 UTC      |
| Local       | 2023-11-14 17:13:20 UTC-05:00 |
| ISO 8601    | 2023-11-14T22:13:20.000Z     |

Known Issues

• Only detects plain numeric Unix timestamps (not ISO strings or other formats).
• Negative timestamps before 1970 may not be parsed by the regex.
