About Unix Timestamp Converter
A Unix timestamp counts the seconds since 1 January 1970 00:00:00 UTC. It's how most databases, logs and APIs store time. JavaScript and Java often use milliseconds instead, which are 1,000 times larger.
Frequently asked questions
How do I know if it's seconds or milliseconds?
Today's timestamps have 10 digits in seconds and 13 in milliseconds. The converter detects this for you.
What is the Year 2038 problem?
Systems that store the timestamp as a signed 32-bit number overflow on 19 January 2038. Modern systems use 64-bit numbers and are fine.
