Timestamp Converter
Time /timestampConvert cleanly between Unix timestamps, local wall time, and UTC without pulling in a date library.
Unit
Converted values will appear here.
Choose a mode, enter a value, then convert. local only
How it works
Move cleanly between Unix timestamps, local time, and UTC.
Use it to translate Unix epoch values into readable local and UTC dates.
Example
Convert 1715342400 seconds to 2024-05-10T12:00:00.000Z.
Notes
- MVP supports Local and UTC only.
- Timestamp mode auto-detects seconds vs milliseconds unless you override it.
- Date mode uses the selected timezone when interpreting the input value.
Constraints
- Accepts whole Unix timestamps in seconds or milliseconds within the Date range.
- Limit: One timestamp per conversion. Nothing is uploaded or silently truncated.
Common errors
- Non-integer input
- Seconds mistaken for milliseconds
- Date outside browser range
When to use it
