A UNIX timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970, at 00:00:00 Coordinated Universal Time (UTC). This tool helps you convert these timestamps to human-readable dates and vice versa.

• UNIX to Human-Readable: Enter a UNIX timestamp (assumed to be in milliseconds). Select your desired timezone, and the tool will display the corresponding date and time in that zone.
• Human-Readable to UNIX: Enter a date and time. This input is interpreted based on your browser's local timezone settings. The tool will output the corresponding UNIX timestamp in milliseconds (UTC).
• Timezones: The timezone list is populated based on your browser's capabilities (`Intl.supportedValuesOf('timeZone')`).
• Current Time: Inputs default to the current time when the page loads or when cleared.

All conversions are performed locally in your browser.
