Unix Timestamp Converter
Converts between epoch seconds, milliseconds, ISO 8601 and human dates in any timezone.
A Unix timestamp in, a readable date out — and the other way round. It reads seconds, milliseconds, microseconds and nanoseconds, and tells you which it decided your number was, because a timestamp with the wrong number of digits is off by a factor of a thousand and lands in 1970 or in the year 55000.
Read as Seconds from its magnitude. Override above if that is wrong — a 1970 timestamp in milliseconds looks like a 1970 timestamp in seconds.

How to use it
Paste the number
The unit is guessed from the magnitude — ten digits is seconds, thirteen is milliseconds — and stated on screen so you can correct it if the guess is wrong.
Read it in the timezone that matters
UTC, your own zone and any zone you pick are shown together. A timestamp is a single instant; only its rendering has a timezone.
Or go the other way
Type a date and time and get the timestamp back, in whichever unit your database or log format wants.
Common questions
My timestamp shows 1970. What went wrong?
A millisecond value was almost certainly read as seconds, or the value is genuinely zero. 1970-01-01T00:00:00Z is the epoch itself, and it is what an uninitialised or missing timestamp usually turns into.
What is the 2038 problem?
A signed 32-bit second counter overflows on 19 January 2038 and wraps to 1901. Nothing here is 32-bit, so the conversion is fine — but a system you are feeding might not be, which is worth knowing before you store a far-future date.
Are leap seconds included?
No, and no Unix timestamp anywhere includes them. The epoch counts 86,400 seconds per day by definition, so a leap second is repeated rather than counted. This matters for astronomy and for nothing else you are likely to be doing.
