Frequently Asked Questions
- What is the Unix epoch?
- The Unix epoch is January 1, 1970, 00:00:00 UTC. All Unix timestamps are measured as the number of seconds (or milliseconds) elapsed since that moment.
- How do I tell if a timestamp is in seconds or milliseconds?
- If the number has 10 digits (like 1700000000), it's in seconds. If it has 13 digits (like 1700000000000), it's in milliseconds.
- What is the Year 2038 problem?
- 32-bit systems store Unix time as a signed integer that maxes out on January 19, 2038. After that, timestamps overflow. Most modern systems use 64-bit integers to avoid this.
