Quick answers
How does the converter detect timestamp precision?
Values up to 10 digits are treated as seconds. 11 to 13 digits are milliseconds, 14 to 16 are microseconds, and longer values are nanoseconds.
How do I convert epoch milliseconds to a date?
Paste the 13-digit value. The converter divides by 1,000 and shows the date in your timezone, in UTC, and as ISO 8601.
Can I paste a whole log line?
Yes. The converter reads the first 10 to 19 digit number, a Discord <t:…> code, or an ISO date that ends in Z or an offset. ISO dates without a timezone are skipped because they don't name a single moment.
Is Unix time stored in UTC?
Yes. Unix timestamps represent an instant in UTC. The displayed local time changes by timezone, but the instant stays the same.
