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 widely used in server logs, API responses, and database time fields.
How many hours ahead of UTC is a given time zone?
It depends on the time zone. For example, Korea Standard Time (KST) is UTC+9, meaning you add 9 hours to UTC to get the local time.
How do I convert a millisecond timestamp?
JavaScript's Date.now() and Java's System.currentTimeMillis() return milliseconds. Divide by 1000 to get seconds.
