Verified Developer Solution • 100% OfflineFix "time out of range" / Year 50000+ bugs
Solve bizarre dates in the far future caused by timestamp unit confusion (milliseconds vs nanoseconds).
Your parsed dates are showing up as the year 54,000 or you receive a "time out of range" exception in your language of choice. This happens when you pass nanoseconds or microseconds into a function expecting milliseconds.
Determine the length of your epoch integer. 10 digits = seconds. 13 digits = milliseconds. 16 digits = microseconds. 19 digits = nanoseconds. Divide accordingly before parsing.

Frequently Asked Questions
Q:Where do nanosecond epochs come from?
Languages like Go (time.Now().UnixNano()) and some database systems emit timestamps in nanoseconds for high precision.
Q:How do I debug these huge numbers?
Our Epoch Converter automatically detects seconds vs milliseconds to help prevent these mistakes.
