Usage Guide

Timestamps represent an absolute moment as a number, commonly in seconds, milliseconds, microseconds, or nanoseconds. Paste a value into the input field to see the corresponding local time and UTC result, or enter a local or UTC date and time to generate Unix timestamps for API payloads, logs, and scheduled jobs. When debugging, do not only check whether the date looks close; also compare hours, minutes, and timezone assumptions. Many production issues come from treating seconds as milliseconds, treating UTC as local time, or converting around daylight-saving boundaries without a clear policy.

Examples

• Convert 1715587200 as seconds to identify the local time shown in logs.
• For a 13-digit API value, start with milliseconds, then recheck the unit if the date looks impossible.
• Enter a target date first when you need timestamp values for API test data.
• During cross-region incident analysis, compare UTC and local time to avoid mistaking timezone offset for latency.

FAQ

• What is the difference between 10 and 13 digits? 10 digits usually means seconds; 13 usually means milliseconds.
• Why does the database show a different time? The database, server, and browser may use different default timezones.
• Can future timestamps be converted? Yes, as long as the value is within a reasonable range.
