Unix Timestamp Market Time Converter
Convert Unix seconds to UTC, device time, and four exchange time zones.
How it works
Enter a Unix timestamp in whole seconds, or choose Current time to fill the current instant. Zero is a valid timestamp. Clear the field to remove the value and show an input message.
The page shows the instant in UTC and your device time zone, followed by time and normal session windows for NYSE, LSE, SSE, and TSE. Tokyo and Shanghai show separate morning and afternoon windows with the lunch break between them.
The status estimate checks the exchange's local weekday and clock time against its normal session windows. The date conversion uses IANA time zones, so daylight saving changes are applied automatically without converting formatted clock text back into a date.
Use the result to compare clock times for an instant. Check official exchange notices and calendars for holidays, early closes, trading halts, auction phases, or confirmation of live trading availability.
Step by step
- Enter a timestamp in whole seconds
- Review UTC, device time, and exchange cards
- Check the normal weekday window estimate
Worked example
For Unix timestamp 1719842400, the UTC instant is July 1, 2024 at 14:00. This is a Monday during daylight saving time in New York and London.
The converter shows 10:00 in New York, 15:00 in London, 22:00 in Shanghai, and 23:00 in Tokyo. New York and London fall inside the usual session windows. Shanghai and Tokyo fall outside their session windows at those times.
When to use this converter
Use this converter to view one Unix timestamp in UTC, your device time zone, New York, London, Shanghai, and Tokyo. It is useful when reading dated market data or comparing event times across exchanges.
For a particular trading date, check the exchange's official calendar and notices. This page estimates only normal weekday session windows and does not confirm live trading status.
Common mistakes
A common error is entering a millisecond timestamp as seconds. Divide milliseconds by 1000, round to the nearest whole second, then confirm the displayed UTC instant matches the source timestamp closely enough for your use.
Another error is treating the session badge as a live open indicator. The estimate only checks a weekday clock window. Verify the official exchange calendar and notices for a specific trading date.
Time conversion and session estimate
Instant = January 1, 1970 at 00:00 UTC + timestamp seconds.
Displayed time = format the instant with the selected IANA time zone and page locale.
Within normal session estimate = weekday and time inside any listed session interval. Session close is excluded.
SSE and TSE use two session intervals separated by their lunch break.
A timestamp identifies the same instant everywhere. Only its displayed date and clock time change by time zone. The fixed session windows are applied to past, present, and future timestamps. The result does not use historical calendars, holiday schedules, or live exchange data.
Limitations and assumptions
The converter applies fixed normal weekday session windows to every timestamp: NYSE 09:30 to 16:00 in America/New_York, LSE 08:00 to 16:30 in Europe/London, SSE 09:30 to 11:30 and 13:00 to 15:00 in Asia/Shanghai, and TSE 09:00 to 11:30 and 12:30 to 15:30 in Asia/Tokyo. These are not historical calendar records or guaranteed future schedules. Weekends are excluded by the weekday check. Holidays, early closes, halts, auction details, and live market availability are not checked. Times use IANA time zones and the requested locale; local display uses the device time zone. Enter whole seconds, not milliseconds. Timestamps outside 1900 through 9999 are rejected.
Key terms
- Unix timestamp
- Whole seconds elapsed since 00:00 UTC on January 1, 1970.
- Normal session window estimate
- A clock window that repeats on normal weekdays. This tool does not include an exchange holiday calendar.
- IANA time zone
- A named time zone identifier such as America/New_York. It supplies the daylight saving rules used for conversion.
Compare related tools
Cron Market Scheduler creates recurring schedules for modeled exchange windows. This converter displays one timestamp in exchange time zones. It does not create schedules or account for exchange calendars.
Use the converter to check what a fixed instant looks like in several locations. Use the scheduler separately when planning recurring clock times, and verify the exchange calendar before acting.
FAQ
What does a Unix timestamp represent?
A Unix timestamp counts seconds from 00:00 UTC on January 1, 1970. The converter adds the supplied seconds to that fixed instant, then formats it for UTC, your device time zone, and the four exchanges.
Is timestamp zero valid?
Yes. Zero represents 00:00 UTC on January 1, 1970. The input accepts zero and shows the corresponding date rather than treating it as empty.
Does the status confirm that an exchange is open?
The cards apply fixed normal weekday session windows to every timestamp, including past and future dates. They exclude weekends, but do not check historical calendars, holidays, early closes, halts, or auction details. The estimate cannot confirm whether an exchange is actually open.
How are daylight saving time and my local time handled?
The exchange cards use each exchange's IANA time zone, which applies daylight saving rules where relevant. Your local time uses the device time zone. The display format follows the selected page language.
Which regular session windows are shown?
The normal weekday windows shown are NYSE 09:30 to 16:00 New York time, LSE 08:00 to 16:30 London time, SSE 09:30 to 11:30 and 13:00 to 15:00 Shanghai time, and TSE 09:00 to 11:30 and 12:30 to 15:30 Tokyo time.
