Frequently Asked Questions
What's the difference between seconds and milliseconds?
Unix timestamps are in seconds (10 digits), while JavaScript uses milliseconds (13 digits). Just multiply seconds by 1000 to get milliseconds. Most modern APIs use seconds.
What timezone is the current time in?
The "Current Time" shows your local timezone from your browser. The "UTC" time is Universal Coordinated Time (same everywhere). Both update in real-time.
When does the timestamp overflow?
32-bit timestamps overflow in 2038 (around January 19). Most systems now use 64-bit, good until year 292,277,026,596 - so you're safe for a while!
How do I convert timestamps in Excel or Google Sheets?
In Excel: =(A1/86400)+25569 (for seconds). In Google Sheets: =(A1/86400)+25569. Note: Excel uses 1900 base, Unix uses 1970. Our tool handles all this automatically!
About the Timestamp Converter
A Unix timestamp counts the seconds since 1 January 1970 at 00:00 UTC. Computers use it to store dates without time zone confusion.
How to use it
- 1 Paste a timestamp, or pick a date and time.
- 2 See the converted value in UTC and your local time.
- 3 Copy the format you need.
Frequently asked questions
Is a timestamp in seconds or milliseconds?
Unix time is in seconds (10 digits today). JavaScript and many APIs use milliseconds (13 digits). The converter detects both.
What is the year 2038 problem?
Systems that store Unix time as a signed 32-bit number overflow on 19 January 2038. Modern systems use 64-bit numbers, which last for billions of years.
Does a Unix timestamp have a time zone?
No. It always counts from UTC. The time zone is applied only when the timestamp is shown as a date.
