FAQ: Common Questions
Q: What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) since 1970-01-01 00:00:00 UTC (epoch). It is widely used in servers, databases, and log systems. It has become the de facto standard for time storage because it is independent of time zones and easy to calculate.
Q: How to convert timestamp and date string to each other?
With DevToolbox Timestamp Converter: Paste timestamp or date → automatic conversion in both directions. Programming languages can also be used: JS `new Date(1719187200 * 1000)`, Python `datetime.fromtimestamp(1719187200)`.
Q: What is the difference between 10-digit and 13-digit timestamps?
10 bits = seconds accuracy (2014-2030 range), 13 bits = millisecond accuracy. JS Date uses milliseconds (Date.now() returns 13 digits), Unix shell `date +%s` returns 10 digits. Pay attention to multiplication and division by 1000 when converting each other.
Q: What is the problem in 2038?
The maximum representation of a 32-bit integer timestamp (4 bytes) is 2038-01-19 03:14:07 UTC, which will overflow if exceeded. 64-bit systems are not affected, but embedded and older systems may experience it. Workaround: Use a 64-bit integer or string.
Q: What type does MySQL use for timestamps?
The MySQL TIMESTAMP type stores Unix timestamps (seconds) in the range 1970-2038. DATETIME stores date and time strings in the range 1000-9999, **DATETIME** is recommended (no 2038 issues).
