Date and time
Timestamp to Date Converter: UTC and Local Time
A timestamp to date converter is helpful when logs and APIs show machine-friendly time but you need the human date. Seeing UTC and local time together prevents many debugging mistakes.
Use the free Timestamp ConverterCheck seconds versus milliseconds
Unix seconds are often 10 digits, while JavaScript milliseconds are often 13 digits. Choosing the wrong unit can make the converted date look impossible.
Use UTC for server logs
Backend logs and API events are commonly stored in UTC. UTC makes events easier to compare across servers, regions, and teammates.
Use local time for human schedules
Local time is easier when checking meetings, publish times, reminders, or customer-facing events in your own timezone.
FAQ
How do I convert a timestamp to a date?
Paste the timestamp into the converter. It will show readable UTC time, local time, Unix seconds, and Unix milliseconds.
Why does the same timestamp show different local times?
Local time depends on the device timezone. UTC stays the same everywhere.
Can ISO dates be converted to Unix time?
Yes. Paste an ISO date string to get Unix seconds and milliseconds.
