Random Time Generator

What it does

The Random Time Generator draws random clock times between a start and end time — in 12-hour or 24-hour display, with optional seconds and milliseconds. It’s the time-of-day counterpart to Random Date: for shift boards, schedule mockups, and any fixture that needs plausible clock values inside business hours (or deliberately outside them).

Common use cases

• Schedule and calendar mockups — appointment and event times confined to a realistic window (09:00–17:00).
• Test fixtures — time columns at controlled precision, including the millisecond values that expose formatting bugs.
• Time-parsing tests — 12-hour vs 24-hour renderings of the same seeded values make conversion tests trivial.
• UI states — timestamps for chat mockups, logs, and notification lists.

Settings

• Start / End time — the inclusive daily window values are drawn from.
• Format — 12-hour (AM/PM) or 24-hour display.
• Include seconds / milliseconds — precision toggles.
• How many — batch generation, exportable as text, CSV, or JSON.
• Seed — the same seed and settings regenerate identical times; your local clock is never involved.

Privacy note

Times are generated locally in your browser and never uploaded — random clock values, not records of anything.

FAQ

Does it use my current time? No — output depends only on your configured range and seed, so fixtures are stable across machines and days.

Can the range cross midnight? Set the window to the hours you need; for overnight scenarios, generate the two segments (e.g. 22:00–23:59 and 00:00–06:00) and combine.

Full timestamps instead? Random Datetime draws date+time values with ISO/Unix formats; Random Date handles calendar dates alone; Random Schedule builds whole event calendars.
