Identifier & Time Tools

Use these tools when a value identifies an object or an instant in time. Validate UUID format and version separately from application meaning, and make timestamp units and timezone offsets explicit before comparing dates across systems.

Common workflow

Where to start

2 recommended starting points

Step 1

UUID

Generate random UUID v4 or time-ordered UUID v7 values, validate UUID versions, and inspect embedded UUID v7 timestamps locally.

Open UUID

Step 2

Timestamp

Convert Unix timestamps in seconds, milliseconds, microseconds, or nanoseconds and parse ISO 8601 dates. Inputs without an offset use UTC.
