Why does my timestamp show 1970?

A value near zero maps to January 1, 1970. Often the value is milliseconds being read as seconds - divide by 1000.

32-bit signed timestamps overflow January 19, 2038. Modern 64-bit systems are safe for billions of years.

Convert timestamp in JS/Python/PHP?

JS: new Date(ts*1000).toISOString(). Python: datetime.fromtimestamp(ts,tz=timezone.utc). PHP: date(Y-m-d,ts).

Frequently Asked Questions

What is a Unix timestamp?▾

A Unix timestamp is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It is a universal integer representation of any moment in time, independent of timezone. For example, 1700000000 is November 14, 2023, 22:13:20 UTC.

Why does my timestamp show a date in 1970?▾

A value near zero maps to January 1, 1970. Common causes: the value is in milliseconds but treated as seconds (try dividing by 1000), or the field was never set and defaulted to zero. The epoch reference point is timestamp 0.

What is the difference between seconds and milliseconds timestamps?▾

Seconds: 10 digits (e.g. 1700000000). Milliseconds: 13 digits (e.g. 1700000000000, 1000x larger). Microseconds: 16 digits. JavaScript Date.now() returns milliseconds. Python time.time() and most databases return seconds.

When will Unix timestamps overflow — the Year 2038 problem?▾

32-bit signed integer timestamps overflow on January 19, 2038, 03:14:07 UTC (max value 2,147,483,647). After that the value wraps to a large negative number. Modern 64-bit systems are safe for hundreds of billions of years.

How do I convert a Unix timestamp in JavaScript, Python, or PHP?▾

JavaScript: new Date(timestamp * 1000).toISOString()
Python: datetime.datetime.fromtimestamp(ts, tz=datetime.timezone.utc)
PHP: date('Y-m-d H:i:s', $timestamp)

Current timestamp — JS: Math.floor(Date.now()/1000) Python: int(time.time()) PHP: time()
