Timezone explorer

Search 500+ IANA zones.

Clicking a timezone applies it across every converter on this page.

Timestamp → Date

Decode epoch values with timezone-aware formats.

Enter a valid numeric timestamp.

Date & Time → Timestamp

Build precise timestamps for scheduling and logging.

Select a date to convert.

Natural Language → Timestamp

Parse phrases like “next Friday 5pm” or “in 3 hours”.

Enter a phrase like “next Friday 5pm”.

Relative Difference

Compare two timestamps or measure distance from now.

Enter a reference timestamp.

Batch Timestamp Conversion

Paste timestamps (optionally with precision) one per line.

Conversion History

Stored locally in your browser (max 40 entries).

No saved conversions yet. Use the save buttons to keep important results.

Performance Tips

  • Use microsecond or nanosecond precision when analysing high-frequency log streams.
  • Export batch results to CSV/JSON for further processing in spreadsheets or pipelines.
  • Clear history before sharing your screen to keep sensitive timestamps private.

Scheduling Hacks

  • Combine natural language parsing with timezone switching to plan meetings globally.
  • Use relative differences to track countdowns to product launches or SLAs.
  • Share timestamp URLs with stakeholders to recreate exact conversion settings.

Power User Ideas

  • Bookmark parameterised URLs to create reusable presets for teammates.
  • Run error logs through batch conversion to align incidents with human-readable times.
  • Copy ISO outputs directly into API payloads, database seeds, or audits.

How to use the Timestamp Converter

This tool provides a complete workflow for working with UNIX timestamps and human-readable dates. Each panel is reactive: update any field and the results refresh instantly without reloading the page.

Live dashboard & timezone explorer

  • Live UNIX timestamp: Watch the current epoch clock (seconds → nanoseconds) update every second.
  • Use now: Press the blue button to prefill every converter with the current moment.
  • Timezone explorer: Search any IANA timezone. Clicking one applies it to all converters, history entries, and batch previews.

Convert timestamp → date

  1. Paste or type a numeric timestamp and choose its precision (seconds, milliseconds, microseconds, or nanoseconds).
  2. Select the display timezone to see formatted outputs for that region.
  3. Copy any format (ISO, UTC, relative, etc.) or save the result to history for later.
  4. Use the quick timezone comparison grid to verify the same instant across popular cities.

Convert date & time → timestamp

  1. Pick a calendar date and an accurate time (seconds supported).
  2. Choose the timezone the date/time should be interpreted in.
  3. Copy the resulting seconds/microseconds/nanoseconds or the formatted ISO strings. Saving adds the entry to your local history.

Natural language parsing

  • Enter phrases such as “tomorrow 7pm PST”, “next Friday at 09:00”, or ISO-like strings.
  • Select the timezone to render the interpreted result.
  • All formats and calendar facts become available for copy/save once the phrase is valid.
  • If parsing fails, an inline message suggests rephrasing with more precision.

Relative difference analysis

  1. Enter the reference timestamp and its precision.
  2. EITHER tick “compare with the current time” OR specify the comparison timestamp + precision.
  3. Pick a timezone to display both endpoints in readable form.
  4. Review the summary card plus multi-unit breakdown (seconds → years) to understand elapsed time.

Batch conversion workflow

  • Paste one timestamp per line. Optionally append a precision keyword (e.g. 1700000100 seconds).
  • Toggle the preview to inspect conversions or error rows. Successful rows show the formatted datetime and ISO string.
  • Copy the table, export as CSV/JSON, or load the sample dataset for quick testing.
  • Upload text/CSV files; the tool reads them client-side, preserving privacy.

History management

  • Saved conversions persist in browser storage (no server sync).
  • Use the restore button to reload parameters into the converters.
  • Copy the stored ISO string or remove entries individually. “Clear history” wipes everything instantly.

Productivity tips

  • Bookmark URLs generated via the “Share” buttons to create reusable presets for teammates.
  • Run incident logs through the batch converter to reconcile timestamps with human-readable times.
  • Use natural language parsing for quick scheduling then copy the ISO output to API payloads or documentation.

Everything runs entirely in your browser, so no timestamps ever leave your device. Combine these panels to plan releases, audit logs, coordinate global teams, and troubleshoot time-sensitive issues with confidence.
