This tool helps you convert various time formats:

• Input Timestamp/Date String: Enter a Unix timestamp (in seconds or milliseconds), an ISO 8601 formatted date string (e.g., 2023-10-27T14:30:00Z, 2023-10-27T10:00:00-04:00), or many other common date string formats (e.g., May 12, 2025 at 10:15:06 PM UTC-7, 2025/09/08 02:00 GMT+2). The tool will attempt to parse a wide variety of inputs.
• Select Input Type (Optional): 'Auto-detect' is usually sufficient. If your input is ambiguous (e.g., a number that isn't clearly seconds or milliseconds), you can specify the type.
• Specify Assumed Timezone (for date strings without an offset): If you enter a date/time string that does NOT contain timezone information (e.g., 2023-10-27 10:00:00), you can use this dropdown to specify which timezone that date/time should be interpreted in. It defaults to UTC. This dropdown is hidden if the tool successfully parses timezone information directly from your input string (like 'Z', '+02:00', or 'GMT+5').
• View UTC & Unix: The tool will display the input as a full UTC date/time string and its corresponding Unix timestamp values (in seconds and milliseconds).
• Add Target Timezones: Click "Add Target Timezone/Offset".
• Select Target Offset/Zone: For each target, select a UTC offset (e.g., UTC-05:00), a common timezone (e.g., America/New_York), or a recently used zone from the searchable list.
• View Conversions: The converted date and time for each target will update automatically.

Developers frequently encounter different time representations:

• Unix Timestamp: The number of seconds (or milliseconds) that have elapsed since January 1, 1970, at 00:00:00 Coordinated Universal Time (UTC). It's a common way to store time in databases.
• ISO 8601: An international standard for representing dates and times. Examples: 2023-10-27T17:30:00Z (Z for UTC), 2023-10-27T12:30:00-05:00 (UTC offset of -5 hours).
• Other Date Strings: Many systems or logs might use other human-readable formats, like 12 May 2025 10:30 PM EST or 2024/01/15 14:00:00 GMT+0200. This tool attempts to parse many common variations.
• UTC (Coordinated Universal Time): The primary time standard by which the world regulates clocks and time.

This tool helps you easily translate between these formats and view them in specific timezones or offsets.

• Always Clarify Source: When given a timestamp or date string, confirm its original timezone or if it's intended as UTC. Ambiguity is a common source of bugs. This tool tries to be flexible, but explicit information is always best.
• Be Wary of Local Time: Server logs might be in UTC, server local time, or another timezone. Application timestamps might be stored differently.
• Use ISO 8601 with Offsets: When exchanging date/time information, prefer ISO 8601 strings with explicit UTC offsets (e.g., -07:00 or Z) to avoid confusion.
• Unix Timestamps are UTC: By definition, Unix timestamps represent a moment in UTC.
• Check Parsed UTC: Always verify the 'Parsed Input (UTC)' section to ensure your input string was interpreted as you expected before relying on target conversions.
