Timestamp Converter
Convert between Unix timestamps and date/time
Current Unix Timestamp
Timestamp → Date
Date → Timestamp
Overview
Convert between Unix timestamps (seconds or milliseconds) and human-readable dates in both directions. When analyzing API logs or debugging database records, you often need to read a raw timestamp quickly -- this tool handles that. It also shows the current time as a live timestamp.
Key Features
- Unix timestamp to date/time conversion
- Date/time to Unix timestamp conversion
- Automatic detection of seconds vs. milliseconds
- Live display of the current timestamp
- Toggle between UTC and local timezone
How to Use
- Enter a timestamp to see it converted to a date and time.
- Or select a date and time to compute the corresponding timestamp.
- Choose seconds or milliseconds, or let auto-detection handle it.
- Switch between UTC and your local timezone to compare.
Tips
- 10 digits usually means seconds; 13 digits means milliseconds.
- JavaScript Date.now() returns milliseconds, while Python time.time() returns seconds with decimals.
- The Y2K38 problem causes 32-bit timestamps to overflow on January 19, 2038. 64-bit systems are unaffected.
FAQ
- What exactly is a Unix timestamp?
- It is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC (the Unix Epoch). Because it represents the same moment regardless of timezone, it is widely used for time synchronization across systems.
- Are negative timestamps valid?
- Yes, negative timestamps represent dates before January 1, 1970. For example, -86400 corresponds to December 31, 1969.
- Does the timestamp value change depending on timezone?
- No. The timestamp itself is always based on UTC, so the number is the same in every timezone. Only the human-readable date and time change with the timezone.
