Frequently Asked Questions (FAQ)
What is Epoch time?
Epoch time (Unix timestamp) represents the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to store dates and times in systems and databases.
What's the difference between 10-digit and 13-digit Epoch?
10-digit: Timestamp in seconds (e.g., 1609459200)
13-digit: Timestamp in milliseconds (e.g., 1609459200000)
JavaScript's Date.now() returns 13 digits (milliseconds), while most backend systems use 10
digits (seconds).
What's the difference between KST and UTC?
KST (Korea Standard Time) is UTC+9. When it's 12:00 in KST, it's 03:00 in UTC. Epoch timestamps are UTC-based, so timezone conversion only affects display.
How do I convert timezones?
Epoch timestamps are absolute time values independent of timezones. When converting, select your desired timezone to display the date/time accordingly. The timestamp value itself doesn't change.
Can Epoch values be negative?
Yes! Negative Epoch values represent dates before January 1, 1970. For example, -86400 represents December 31, 1969.
How do I use it in JavaScript?
Current time as Epoch: Math.floor(Date.now() / 1000)
Epoch to Date: new Date(epochSeconds * 1000)
Date to Epoch: Math.floor(date.getTime() / 1000)
