Unix timestamps do not contain a timezone. Local time uses this device's timezone; ISO is UTC.

Worth knowing

The timestamp itself has no timezone.

Unix time is just a count from 1 January 1970 UTC. OutMonkey shows the same moment in your device's local timezone and as ISO/UTC so you can copy the version the next system expects.

Before you use it

Seconds and milliseconds look very different.

Ten-digit timestamps are usually seconds; thirteen-digit timestamps are usually milliseconds. Auto-detect handles both, but you can force the unit when an API uses something unusual.

The annoying bit

The date is apparently 1788847342.

Machines love timestamps. Humans generally prefer Tuesday at 3:14 pm. This is the translation layer.
